I think winning streaks can lead to overconfidence in gamblers and result in riskier and more impulsive bets. This can lead to losses if the gambler continues to take bigger risks and does not stop before losing everything they have won. Additionally, winning streaks can also lead to a false sense of control, where the gambler may believe that they have some sort of control over the outcome of the game, leading to further risky bets in the future.
