What causes the experienced house or player edge?
Go to a brick and mortar casino and make 100 bets a 10$:
A) The croupier doesn't reduce a house edge from every bet
B) After you have wagered 1,000$, the croupier also doesn't say that you have to give him now the house edge for the 1,000$ you have wagered

When you end the session, the total number of bets won is your experienced win or the total number of bets lost is your experienced loss, simple.
