While this is impossible for a single hand, this will be the expected value over the long run.However, the hold percentage is in fact much larger. If the house edge in a game of blackjack is 1%, the house will keep on average 1p from every $/€1 bet by the player. Hold percentage is distinct from house edge, which simply dictates the expected return from one individual game.
