There are some exceptions though, that often seem to slip people's attention. Meaning that you need a win rate of more than 52.4% of your bets in order to make a profit (assuming -110 odds). The break even winning percentage of a profitable sports bettor is typically 52.4%. Professional sport bettors rarely sustain long-term winning percentage above 56% and sometimes the lowest win rate of 53 – 54 %.

Many people say that the best professional sports bettors - such as Billy Walters - have won of 58% of their sports wagers.
