Money management can extend the life of the deposit, but you will not change the likelihood of losing in any way. The advantage of a casino is a constant indicator in any game (in the sense that a player cannot influence it). All these strategies and tricks taught by experienced players to beginners (often for money) are self-deception.
I agree with that, I was deceived that I can regain my losses through playing martingale because I can see that by doubling up you can regain all your losses with one bet, but it did not explain that I need a large bankroll so I can keep up, it took me some games before I realized that it will not work all the time, you can him some time but most of the time the strategy will not work.
