When we are losing in gambling, it doesn't mean we can continue to play the game because it will make us become a stress to see how much money we lose. That will make us feel that we have a big problem because of losing the money and that will make our brain will full of the stress, and when we see the amount of the money, it will add more stress to us because we could think how we are going to recover that loss.
You are talking about the psychological scenario of a gambler. Normally people think it is good to treat gambling as a way of pure entertainment but not everyone think like that and many people try to make money at gambling which often leads them to loss and the urge to recover the losses make them more prone towards loss which is a dangerous situation for gamblers. So yeah, in such a case, you can say that gambling is equivalent to eating up your brain.Yes, the psychological scenario will give an effect to the gambler itself whether they can win or they are losing the money. But indirectly, when they see other people can win in one game, they will think that they can get win too. And that will make us have a big passion for continuing the game, and if we cannot win, then we will be stress. That will be their problem if they cannot treat gambling as a way to have fun and in the end, they will only lose more and more money, and they can become addicted.
