EV betting means placing bets where the probability of winning is higher than what the sportsbook's odds imply. It's like getting +110 odds on a coin flip: the math is in your favor. If our model estimates the true probability of an outcome at 60% but the book is offering odds that imply only 52%, you have a +EV edge. Over a large sample of +EV bets, the math works in your favor, though individual outcomes will vary and no result is guaranteed.
