That is possible to happen but you don't have to think much about RTP. You can enjoy the slot games for some time and then stop gambling. RTP doesn't guarantee you win but your luck. If you don't have luck, you will difficult to win.

Maybe that is right that high RTP can give you much return. But if you don't have luck, that will not happen. You just need to think about how you can enjoy your time in gambling and not think about winning because that is difficult.

I never check on the RTP but sometimes, members here share the RTP. But you don't have to think much about that.
