There are a variety of reasons why blackjack dealers always win, but the main reason is that they have a better understanding of the game than the players. Blackjack is a game of chance, and as such, it is impossible for players to have an overall advantage over the dealer.
In contrast, blackjack dealers have learned how to play the game in such a way that they are almost always guaranteed to win.
One of the first things that dealers need to do is understand how to read the players. They need to know what cards the players are likely to hold, and what cards will give them the best chance of winning. Dealers also need to know when to stick with their strategy and when to make a change.
If a player hits on all 8s, for example, it might be worth sticking with that strategy even if another player starts hitting high-card values. However, if another player starts hitting low-card values, it might be worth switching to a different strategy in order to increase your chances of winning.
Dealers also use a number of other factors in their decision-making process. For example, they may choose to stand if they believe that the player holding a high-card value is going to hit on that particular hand.
In addition, dealers may also use side bets and proposition bets in order to improve their chances of winning.
