I have never experienced winning in gambling in large numbers. Usually I always play a small amount, because I'm always afraid when playing with a large amount. Not that I do not want to win big, because we know for yourself that the risk of playing gambling must be huge too
Basically there are many games where you can win big with small bets only. Indeed the probability to win big with small bet is just so low and it may eat your balance small by small amount but this is the only way to win big with small bets. We should take a risk on a game with big payout but low winning chance. I do not recommend it though, it is just what I usually do because I'm small gambler as well.
