The balance between luck and skill in poker varies depending on the game type, player experience, and the duration of play. In the short term, luck plays a significant role, as anyone can win or lose based on the randomness of the cards. However, over the long term, skill becomes far more dominant, as experienced players consistently make better decisions and capitalize on weaker opponents' mistakes. Most experts estimate that poker is around 70-80% skill and 20-30% luck over the long haul. In tournaments or cash games, skilled players tend to outperform luck over time.
