Quick answer: A value bet is one where the true probability of an outcome is higher than the probability implied by the odds. If a team’s real chance of winning is 50% (fair odds 2.00) but a bookmaker offers 2.20, that is value, and betting value consistently is the only way to profit long term.
Why value beats win rate
You can win 70% of bets and still lose money backing poor-value favourites; you can win 40% and profit if every bet is priced above its fair value. The formula: Value = (your probability × decimal odds) − 1. Above 0 is a value bet.
