Of course, this will make them frustrated with the losses they have experienced, especially if the losses were very large. But they only feel this frustration for a short time because when they return to gambling again, they will not feel frustrated but will try to recover their losses. Having financial records about their gambling can actually help them to see how much money they are using for gambling so they can start reducing their gambling activities. But what happens is that there are still many gamblers who don't pay attention to this and instead gamble more often because they have the hope of recovering their losses. This is where they really need to realize that by recording their gambling activities and seeing how many deposits and withdrawals they make, they can conclude that gambling is not suitable for them. They don't need to gamble too often.
