I really don't see how having experience in games like roulette may help you winning. Games like roulette are unpredictable and the outcome is based on a private server seed.
Maybe if you have experience you may already know this and you know the risks of betting.
to me i think there are some formats of gambling where we need our experience and skill. although we are depending on our luck for gambling, but still in some games iike sports betting, horse racing and motor racing we can use our skill and previous experience, while in some other gambling games we are totally depending on our luck and there is no need for any experience and skill.
Not just in betting, I believe almost in all types of gambling you can use your experience. Experience may not help you to make profits in all gambling, but definitely it will help you to prevent losses.
Yes, believe me, before I used to to go for dicing with big bet amount, but after experience I have learnt to go with small bet amounts. This may be an silly example, but if you think how experience works in luck based to gamble, you may realize the fact.
