Usually, people who win in gambling but not able to cash out or save their winnings and I think this has something to do with a Healthy mindset.
If you do not have the intention to save the wealth, you will lose all your winnings by risking them again in another gambling bet.
Only a mentally strong person who has control over emotions and have money management skills would be the real winner here and will become rich eventually.
The sort of people who play the lottery can be quite distinct from other types of gamblers, they may not even see it as gambling in the traditional casino sense of the word. That sort of person may have a better level of financial control and be less impulsive, or susceptible to throwing away all their winnings. There's also quite a big difference in potential outcomes, if a casino player is lucky on a slot game, they might walk away with $1,000 in winnings after betting $2. If a lottery winner bets $2 and gets back $2 million, they are less likely to buy lots more lottery tickets afterwards or it will have a negligible effect on their new found wealth. I think it'd be fairly easy for a lottery winner to walk away from gambling forever after that point and be very happy.
