Casinos rely on the house edge to make money. This is the percentage of the bet that the casino keeps, even when you win. In most cases, this is around 2%. So if you bet $10, the casino would keep $8.
If you were to play blackjack for real and win, you would actually receive $9 back from the casino. However, it is still important to remember that casinos have a lot of tricks up their sleeves to keep you from winning.
So can you beat the casino at blackjack? The answer is yes, but it takes a lot of practice and knowledge. If you can master basic strategy and understand how casinos work, then you have a good chance of winning.
However, even with all of this knowledge, there is always a chance that the casino could catch you by surprise and beat you. So if you’re serious about winning at blackjack, then you’ll need to be prepared for anything.
