Do bookmakers or prediction platforms themselves publish statistics on the percentage of profitable players in relation to all other players? Does this information differ between different sources? Is there a difference in long-term profitable players in bookmakers and on prediction platforms?
I don't think it is in the place of prediction sites to publish such details, they can only know how much traffic that they generated like how many IP address visited their website but not those who actually bet. It is a different thing when you visit a prediction site and actual gambling of what you got. So it is in the hands of casinos to say how many percentage of players are actually long time winners. It is going to be a compilation from different casinos and gambling house put together. But from the general view of gamblers here, it is quite a low number that are consistent in winning. Maybe less than 5% of players are winners.
