For me having a better understanding of gambling make risk lesser in gambling because if there is no understanding in gambling it is impossible for one to understand their is a need to stick to the limits that one can afford to lose. Understanding in gambling makes gambling easy and not of much risky. The first step that will be able to make a gambler to stick their amount that they can afford to lose in gambling is to have understanding of why it is important to stick to the amount you can afford, if you don't have the understanding it is impossible to gamble responsibly.
When we have a complete understanding of the activities We are Involved in we are aware of everything, the money we are risking and the money we can possibly Win , but it is not good to think about what we will win because it is very likely that it will not come due to the fact that we do not always have the same good luck, we have to think about what we can do and fight to get it , when we Know all that and the house advantage our mind works differently and we do not get stressed and thus we play better.
