It is not always easy to accept the loss and move on in gambling. It also depends on how much was used to bey. Some people do.not bey with what they can afford to lose. They stake very high and that is why it is always difficult for them to move on when they lose it. They will continue by chasing their losses by taking some revenge betting which never ended well.
When you gamble with any amount you can afford to lose and take gambling as a fun rather than an investment opportunity, you can always move on whenever you lose.
The main difference between those which gamble for fun and those which gamble to get money is their ability to move on once they lose, those which see gambling as just another hobby can accept their losses and then do something else with their time, but those which want to make it a profession cannot accept the fact they lost money, so they keep gambling hoping to recover what they lost only to face disastrous results as they gamble money they cannot really afford to lose.
