I have come across different numbers. Some argue that only 1% of players are profitable in the long term. Others say that less than 1%. Still others claim that the number of such players is 0.01%.
I have found out the percentage of gamblers that are losing before, but I have seen sites that said 90 to 95% while also some said 3 to 5% and some said 4% and so on. What I noticed was that almost all gamblers are losing.
I do not think that is a long term estimate because if it is long term, I guess the percentage will be less than 4%. This is not what we should bother about unless will have something to write about it like a project or news or something like that.
