How can people win in a blackjack without counting?

Blackjack odds are considered the probability of winning that hand in the game. Blackjack odds vary with the number of decks in play, the house rules, and even the cards which have been dealt already. Other games in casinos depend purely on luck, but blackjack combines chance and skill. Knowing the odds increases your chances of winning and helps you make better decisions in knowing when to hit or stand, split or double down.
