I think many successful casino players do rely on context in their decision making. They analyze factors such as the game being played, the odds, the amount of money they are willing to risk, and any patterns that may influence the outcome. Experienced players also pay attention to their own emotions, as well as the behavior of other players and the dealer, in order to make more informed choices. Ultimately, both luck and skill play a role in casino games, and players who can balance both have a higher chance of success.
