In gambling in general and in sports betting in particular, bankroll management is very important. It is really important because it helps to avoid financial disaster. But if you play not only for fun and thrills, then we should also remember about strategy. Many people implicitly try to replace strategy with bankroll management. But I think you will agree with me. We forget about strategies all the time. Bankroll management is not a strategy. Bankroll management only helps you not to lose your bankroll immediately. You will lose your bankroll gradually, slowly, but still you will not avoid losing your entire bankroll, because most likely you do not want to know anything about strategies or even replace them with bankroll management.
Do you agree with me? Or do you think that bankroll management is a strategy?
Depends on what you define a strategy as...
A strategy to not lose all your money in 5 minutes? Sure. But that is not a strategy to not lose all your money. Just stretch it out for a longer time. And for the people, like me, who gamble only for fun, that kind of "strategy" is way more useful than trying to convince yourself you found a loophole in mathematics and can somehow outsmart the casino with Martingale or some other so-called strategy.
