You are so categorical!!! I don't think it's right to have a long discussion about this, but I am sure there are players who earn a living exclusively from poker and do not reveal their names; they avoid publicity, or rather, the hype around their name. This does not necessarily mean they are criminals. If you are really interested, you can look for quotes from top players who are well-known and who, without mentioning names (real names, if they know them, and even nicknames), talk about those who are in the shadows and have authority in the player community.
