What betting method are you using, are you trying to hit high multipliers with small bets or the classic martingale? Anyway, there is not a always win method on bets, even the low chance to lose bets can hit back to back, so be careful and hope you can multiply your money until hot the goal.
He is using low winning chance, 20-26% from what i've seen on OP video. It's not martingale, he mixed low and high betting and some % increase after lose.
