that is one of the things some people does not understand in gambling because every gambling website you know today does not have assurance and you participating in them and win is based on Opportunity that come for that moment so I know very well that gambling is all about opportunity but many people who owns a website to will tell you that when you gamble in their website definitely you will win thinking that is a website that guarantee a winning in any gambling website so I do pay my people who can move with me that website cannot make you to win a gambling it depends on your prediction because if you predict the same then website a and in website b you will win the same thing if the winning is for you and if losing is for you you will lose in both side
I think you are right many people do not understand gambling. They believe some websites promise they will win but that is not true. Gambling is about chance and luck. No website can guarantee a win. It depends on our own predictions and luck. Some website owners might say you will definitely win but that is not honest. Whether we win or lose depends on our own choices not website. If we make good choice we will win and if we make bad choice so definitely we will lose. It is good to remember that gambling is game of chance and there is no sure way to win.
