A gambler won a very decent amount of gambling will now probably knows the feeling of being a good winner. If that is the case, they will just continue their gambling activity to feel again that feeling, who doesn't want to feel that again? And the result, all the winning amount will be used in attempting to reached again that achievement. So another risky attempt again and obviously, chances of losing all the winnings have higher percentage.
Everyone wants to feel that again however some will stop and just do it the next day after. Not that it really make any difference at all however those risky attempt still have the same chance as the first one to win alot more. Some people in the end could get alot from casino so it is not really a bad attempt
