So basically, the strategy is to stretch out the gambling session. Well, no one really wins long-term in games with a house edge, so this is a solid suggestion. They say gamble for fun, well, this is exactly that. You get to play longer, and even if you lose in the end, you still feel satisfied because you were entertained. I think only bankroll management in sports betting really gives us a shot at long-term success.
I have never seen much point in playing casino games with a bankroll except for that, to make your money last longer and not gamble it away. If you manage your bankroll well you will be less likely to lose money you can't afford to lose. But it is more typical of skill games, where you can make profits in the long run.
