You're so lucky that I have never been, I have tried several gambling sties but it turned out I'm a super gambling newbie and always lose money.
Thats probably because scared money makes no money. Try thinking of the bets as numbers and not actual money. It helps me a lot in my betting
Only scared money is able to make better decisions, so its not always true that scared money loses all the time.
Well being scared you are hesistant to bet big and lose the opportunity to win big money. But obviously, you can lose as well.
