House edge is expected loss divided by the stated wager amount. A hypothetical 5% edge means $5 expected loss per $100 wagered; actual results vary. Break-even win rate, sportsbook overround, poker rake and pool takeout measure different things. A smaller percentage alone does not establish a better result for a particular player.
