Definitely, I will use martingale strategy because I know, in the end I will win!
Completely wrong, you forget the fact that all casino has limited bankroll which make them limit max win per single bet at a specific number so even if you have infinite bankroll and you do martingale but you reach the max bet/win limit then you have no option to double the last losing bet.
Gambling includes plethora of games, various sports to bet on but doesn't it all boil down to money in the end? More the money involved, more the thrill.
Suppose, as title says — you had infinite amount of money, would you still gamble?
Personally, I can't see myself giving two fucks when I don't care for money in first place. Would you?
Although it is impossible to have infinite amount of money, but if it may happen then there is no more thrill of gambling because there will be no difference when we are losing and winning.
There will be no excitement on winning and there will be no worry on losing which is something not fun at all, so what's the point of gambling when there is feel at all.
