The gambler's emotions can go up and down along with the wins and losses he experiences so if he can't control himself, he can get stuck in a situation he doesn't want. His losses would also be even greater than before, especially when he deposited more money into his account just to continue playing. But that will not prevent the addicted person from depositing money. They will continue to play if they have money in their account or wallet.
I think it's fine to get stuck in the positive side but it's almost impossible to remain there because in gambling, we are mostly prone to losses so our mood can also shift to being negative. It might stay there after some time so the goal is like you said, stop playing for a while and let this bad luck subside first.
There are still ways to be happy outside gambling or even without money involved, if money is the main thing that keeps you coming back in the gambling place. It's only hard to fight the urge once a person is addicted already but they can ask for a help or the people around them can also do actions. If they are truly concerned.
