I can control the desire to gamble and even though for example when I have money but I have no mood to gamble then I won't gamble at that time. Moreover, I do gamble only with small part of my money and if I lost it, I will stop instead of chasing it with my other money.
That's a good control of yourself and not everyone can do it. Once they lost or win they can't keep theirself away from gambling. Eventhough after withdrawal, they will say, okay i'm going to rest in gambling but the fact is they cant so they will make a depo in a few hours or days again and again.
Everyone could control themselves in gambling, the only case here is that they don't to, they are pushing themselves into the edge until they ran out of money. Addicted players on gambling are the most people who doesn't like the term "control", they just want to go all out in gambling, they are like insane people who are selfish and doesn't think of their love ones, they just care about gambling.
I'm afraid to say that they can't stay out of gambling for even just a day, it is their life, without gambling they are just an empty people.
