Majority of people have made money of it already and cannot lose anymore, since everything else is actually not their money anymore.
It doesn't work that way. If a fraudster gives you another investor's money, you don't get to keep it. Every dollar you withdraw is a liability. False profits can be clawed back to repay current "investors". Fraudulent transfers can be undone.
If you received payments from a Ponzi scheme, your interest payments were not in fact interest payments. They were fraudulent transfers of other people's deposits.
