No casino is trying to beat a player on every single wager made. Most games have a house edge of less than 10% and the average casino bet has between 35% and 50% chance of winning.
Known as the house edge, this advantage is not very high and must have a balance between allowing the players to win satisfying amounts while allowing the house to make money. Every casino you play at online makes profit by having a built in advantage on every single game.
