It is not clear what kind of gambling strategy you are talking about, but I assume that gamblers tend to play randomly and change strategies one after another when they lose in any game. Most of the strategies we use in casinos are designed to make the developers win. In any other game gamblers tend to lose the most.

I am not prepared to spend a lot of money on gambling because I know that I will lose most of the time. My strategy is to play more games with small amount money. I am satisfied with my strategy.

Some gamblers may not be satisfied with their own strategy because they are losing most of the time. If they use a more aggressive strategy and they may lose more money.
