I think I was still playing even if I was rich. I play for fun and my basic motive is not to make money to get rich. I enjoy each bet I place. Sports games are like passion for me I just transform this passion to make some money if there is chance. I don't feel need to place on everything. So I was gambling doesn't matter what financial situation I was having.
Gambling is really designed for entertainment and if you want to make this as a living then, you must have the system and discipline in place otherwise, you will surely encounter several losses and may mess your peaceful life. If you are only playing for fun and spend money that you can afford to lose, then status in life doesn't matter at all.
Gambling is designed to bring profit to it's owners, while giving risky short term opportunity to players as well as some entertainment. As for system and discipline, players who want to win consistently should play games where it's possible to have positive expectations, like poker or sports betting, because in typical casino games like Dice or Roulette players can't do anything about their chances.
