Agree to that, even a small chances of winning as long as you deal with it using your knowledge and skills there's a chance that it will happen, you just need to work with it and keep your focus, discipline and allowing yourself to enhance your knowledge from the experience that you gain in each gambling that you made, more on taking time and expanding and exploring with every opportunity that you may have.
There shouldn't be risks taking without careful analysis and knowledge of the indebt effect of that risk, this is very important to all to at least make our plans not to go beyond how far their can bear in terms of the risk, and if a gambler gamble with that line of thoughts, he will definitely be above every trouble waters that can come along with the risks and ending up with some great rewards in the end.
Knowing risk is probably not the same as understanding it, because people would not engage is extremely risky behavior that doesn't benefit them much.
