However, the longer the period we take, the more likely it is that the winners are only people who were lucky. So I wonder what motivates people who want to get rich on sports betting if they believe in such a pattern? Do the players sincerely believe in their own exceptionalism and genius?
No one can be too sure. Truth is that gambling in general is all about luck. It doesn't matter what kind of strategy you think you have or some pattern that you kinda follow to make profits from your gambling, it still falls down to how lucky you are. If eventually you aren't as lucky as you taught, you may end up takings risks that are going to be unfortunate.
as a gambler you don't need to have such a mindset to get rich from gambling. It would ruin you in a way and you may not be able to apply good risk management because you want to risk more and get rich quick...
