A common disease among gamblers is that when they win a bet with a small risk, they regret why they did not bet more, and when they bet with a big risk, they feel disappoint. In such a situation, it is better to manage gambling by placing low risk bets. Because winning and losing in gambling are uncertain. If there is luck, then the gambler will be happy. One should not make one's gambling Unenjoyable by placing high risk bets. When gambling, greed will play negative role, which is why it is best to be able to gamble while keeping greed under control.
This kind of thinking you're talking about is real a lot of gamblers do think that way but I think the real cause of such mindset is greed. When you attach too much greed to your gambling lifestyle you will suffer from indiscipline, indecision and unnecessary pressure from regret and you will not see value for your money.
If you allow such habits gain control over your thought process, you will only suffer the wounds gambling comes with and that's if you don't also suffer from addiction and ou will not always have a good story to tell about gambling like others because of the insecurity that you didn't get what your mind probably to you to get.
