The possibility of gamblers even reaching that maximum winning rate is always very low, but the casino has to set it after all, as they don't want to take chances, and the limit which they set for all players should be to moderate the winning amount, not to exceed their budgeted reserve for winning payouts, any player who tries to bet or stake a game with the exact maximum which the casino set is trying to be greedy and at same time will end up losing it without winning what they targeted.
I have played casino for some years now and it was only once I have hit the maximum multiplier of a casino game which was around 10,000x, unfortunately my bet size was small but the winning was still very attractive. I immediately withdrew the entire winning leaving only my balance prior to the winning. I also took some days off from gambling so I don't end up losing the money back, I had to return to gambling when I have successful invested the money into things I will not easily deposit them back into my gambling account. This helped me to remain calm, maintain my gambling size and plans and not losing the winning.
Winning the max multiplier does not come always, it is something that happens by chance and anyone chasing it might end up losing more money than they plan to lose. I have learnt to gambling without expecting much and if winnings comes, I take it as bonus.
