An edge is the gap between what the math says is true and what a sportsbook is offering. It's the difference between the real probability and the odds they're displaying. When these don't match, that gap is where profitable bets live.
Here's a concrete example: The true probability of an outcome is 55%. But one sportsbook is pricing it like it's only 51%. You're getting better odds than the math says you should. That 4% gap is your edge. You're on the right side of the line.
The Bottom Line: Edges exist everywhere because different books price things differently. When you see an edge on Bethics, this is exactly what you're looking at — a moment where the math favors you.
