Professional? YES!
Famous? NO!
I do know one guy I consider a Professional Poker Player as he doesn't have a day job, He has travelled all over Europe playing in some big Tournaments, and although he has not won any major titles he usually cashes in most of the Tournaments he plays in.
He also owns several Properties in our home town that he rents out through an Agency and they do all the maintenance and repairs, So if he does have a bad run in the Poker scene he can still survive of his rental business.
