Some gamblers are controlled by their wins in gambling. It is not that they are unaware or do not understand what gambling is all about, but after they might have won big in gambling, they are so sure that what they have won can still be achieved again.
This time, they bet with a larger amount, believing that they can still win more. Some people are lucky enough to win again, and this is what gives them more confidence that they can always win in gambling. Gambling again after a win is not really bad, but the reason for gambling again should not be because one was lucky to win, but rather because one is able to afford to gamble again.
Well, that's the mistake. Essentially, we should be playing gambling, not letting gambling play us. As you said, some gamblers are driven by winning. This is true, because many people win and think they can win again and again. Even if they lose in the end, the thought of winning makes it difficult for them to stop.
I believe the thought of winning again is one of the factors that makes many people believe that another win is possible. And yes, those who succeed are lucky, but this is not recommended.
