Whatever the wins money that the gamblers gets will makes them back to playing gambling because at that time, they already started dependence of gambling and they wants to gets wins in the next rounds. Even if that gamblers have a good self control, he can gets tempts of his winning and wants to keeps playing gambling without thinks that he already won. He forgets what he must do when playing gambling and only follows his desires to keeps playing gambling and chase the other winning.
That's ironic but we can't do anything to them because they will not listen to us who always suggest them to prevents their gambling activity not becomes too often. They thinks that they can wins in the next rounds but that will not always happens and they just make many mistakes and difficult to realizes. Maybe they will realizes after they lost everything they have but that's too late because they don't have anything.
Indeed, when they win, they will usually think that it is their lucky day, so there is a big possibility that gamblers will continue gambling and may even lose track of time. The temptation to win at gambling is indeed strong, so it is not surprising that many people are drawn deeper into gambling when they have succeeded in winning, especially if they think gambling is a means that can make them make some money. Of course, when they win, they will not think about cashing it out but continue betting it. but the predictable ending is defeat and will only leave them disappointed.
This is one of the mistakes that gamblers often make, even though they are aware of it and have already experienced it, they could make it again in future gambling. Even though they are aware that they have lost everything, it doesn't guarantee they will stop, whispers about winning will continue to haunt them, but if they can restrain themselves they won't fall into gambling again, it's just unlikely.
