Many people said high gain high risk so if you are not trying to gambling you wont get much money then always stuck in your life like that, never make any progression at all.
I believe this term does not suit gambling at all, IMO. Well, what you said is true, but not everyone is willing to take a big risk. Taking a big risk doesn't mean that the outcome is always great. That is why people always start from the bottom and not from the top.
