No it is gambling with someones else his/her stake at risk. when it gos all well you get your cut but also the first to burn when it gos wrong.
What a very accurate explanation you have here, I assume you've been scammed so many times already if you have this kind of mindset. Not all of the investment sites are legit, not all of the businesses are safe to invest, you have to carefully observe their movement if they are legitimately processing their clients money, you have to consider so many things before you could say that a certain investment site is legit
