Odds for different outcomes in single bet are presented either in European format (decimal odds), UK format (fractional odds), or American format (moneyline odds). European format (decimal odds) are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2.00 are an even bet. UK format (fractional odds) are used by British bookmakers. They are the ratio of the amount won to the stake - the solidus "/" is pronounced "to" for example 7/1 "seven to one". Fractional odds of 1/1 are an even bet. US format odds are the amount won on a 100 stake when positive and the stake needed to win 100 when negative. US odds of 100 are an even bet.
Most losers base their judgement on a subjective feel for the forthcoming event, relying on an inkling or a hunch about what may happen. The skilled tipsters has a huge advantage over the recreational bettor, finding “value” in the odds, where the true chance of a win is greater than that estimated by the bookmaker. Many punters fail to appreciate the importance of value betting, preferring to subscribe to the “back winners, not losers” school of gambling, which will not make you win 57%.
In order to beat the juice and win in sports betting, a bettor must employ a disciplined approach in their analysis of each game using methods that have proven to be successful in the long run. I discuss my math models and analytical metrics in my Handicapping Methods essay, but you must realize that only the best and most knowledgeable handicappers can win more than 52.4% of their games. In their 2007 two page article about my handicapping success, the Wall Street Journal wrote, “…fewer than 100 people can sustain (win rates of 55%) over time. Most of them belong to professional betting syndicates that hire teams of statisticians, wager millions every week and keep their operations secret.”

Transaction costs might shrink, Moskowitz says, if online betting volumes rise and bookmakers increasingly compete. A company dedicated to that proposition is London-listed Paddy Power Betfair (ticker: PPB.UK), whose websites, like Paddy Power and Betfair, processed over $15 billion in sports wagers in 2017. Since we are a stock market publication, we should note that at 8,435 pence ($111.59) a share, Paddy Power Betfair goes for over 20-times this year’s earnings estimate and 14-times cash flow. Revenue grew 13% in 2017, with about half of its revenue from online betting in Britain and Ireland, and about 20% from Australia and on-the-ground casinos. The U.S. is just 6% of revenue, but is growing fast.
So this may have been long and a have little bit of unnecessary info, but I know this field and know what I do and make money doing it. I have lost before and my first profitable season came nearly 3 years into my betting “career”. I lost quite a bit those years but kept working and learning more and better techniques which were showing in my increasing winning percentages. I will still lose over certain sport seasons. I take losses in baseball and basketball the most but still have solid win % in both over 5 years. I may be cocky here, but I believe I won’t lose over a season of college football again. It’s my best sport and do study it more than the others. So if you enjoy the rush of seeing your hard work play out over a few hours or quarters, sports in general, the possibility of losing considerable money and the chance of building profits only dreamed of by traditional financial institution and investing; this may be for you.

A record $4.9 billion was bet, also known as the casino’s handle, on sports in Nevada in 2017, according to the UNLV Center for Gaming Research, growing more than 440 percent from $894,564,000 in 1984, the first year that the figure was tracked. Additionally, sports made up a record 2.15 percent of the state’s overall casino winnings in 2017, up from 0.68 percent in 1984.

ATS equals “against the spread”. The spread is the number oddsmakers use to give people other betting options besides only wins and losses. A spread for a Premier League fixture would be something like .5 or 1.5. One club would need to lose the match by no more than 1 or 2 goals or the other needs to win by 1, 2or more goals.  If the final score doesn’t reflect the number set by the oddsmakers, your bet won’t cover the spread and you can’t win your bet.
