I have different point of view tbh, I will not focus on how much I may lose as well as the potential win but I'll focus more on how to manage my money.
Too much focus on how much you may lose will not good as it will bring negative mindset mindset and can be something stressful for some people.
IMO I do not need to focus on how much I may lose, as long as I always stay on my gambling limit, I dont have anything to worry.
Gambling is about taking the risk for something bigger, if we are not ready to take the risk, we should not even gamble at all than focusing too much on losing probability.
