Beating Blackjack in the long run is possible, but it requires a combination of skills and strategies. Mastering basic strategy, which involves making optimal decisions based on your hand and the dealer's upcard, can significantly reduce the house edge. The real advantage, however, comes from card counting, a technique that allows players to track the deck and adjust their bets when the odds are in their favor. While card counting can give players a slight edge, casinos are well-aware of this tactic and take measures to prevent it, such as using multiple decks and shuffling frequently. Even with these strategies, Blackjack is a game with high variance, meaning that short-term fluctuations can still lead to losses. In the end, while it's possible to beat Blackjack in the long run, it's difficult to do so consistently due to the game's complexity and the casino's countermeasures.
