This is not the only way to make profits
When you bust, all your money becomes casino's. And the bigger the bankroll of a casino relative to your bankroll, the higher are your chances to bust even if the odds are equal, i.e. when there's no house edge as it is commonly understood. Put differently, a bigger bankroll already gives a casino advantage over you, and this is a house edge on its own, and as such it can generate profits in exactly the same way as a regular house edge
