yes youare right.
If you fought hard to become rich and makes a lot of sacrifices just to became rich, then for sure you will never make or do things that will make your hard earned money lose easily, so people who earned their money in hard way mostly didn't do gambling at all.
but for the person who became rich from an easy way, they will more likely spend their money as fast as how they had earned it.
Yes that's true if you are going to work hard for the people of course you don't want it just to lose easily. And you are going to do something just to save it or even make more. And you will even think to gamble that amount because it will just going to lose easily.
