Expected value (EV)
Expected value is the average profit a bet returns in the long run if repeated many times. It is positive when the true win probability is higher than the one implied by the odds.
Example
Odds of 2.00 imply 50%. If your model estimates a 55% win rate, the EV per euro is 0.55×2.00 − 1 = +0.10 (a +10% long term). It does not guarantee the next match.
