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.
An urge for something is meant to keep on recurring in a player's life. It's not just about gambling but multiple other aspects of life, where people deeply get attached to their indulgence in an activity. Some may think it's for the money, yes that may be right. But, for lots of players it may not be due their fascination on money that led them to gamble excessively. Although one could argue that players who are not interested about money can focus on the demo mode, but they're lots of non monetary gaming activities that actually gets players addicted. Video games as an example are naturally addictive, when a player is intrigued about it and wants to always partake in the game. I think it'll be more reasonable if addicts are not being leveled down at all times to be a victim of greediness. Consistency also flows down to addiction.
