Actually, I'm looking forward to this one. I think it could be fun to have a game-within-a-game, & I'm particularly intrigued by the mention of character skill levels affecting the card game (such as Sleight of Hand increasing the coinage gained from cards that allow you to take from the pot or other players).
I do have to wonder about the 50gp per player bit, though. Where the heck is this game played in a RAW-based setting; Fantasy Monaco? Seriously, who other than adventurers or nobles is going to have this kind of money to throw around gambling under the assumed D&D economy? I think they should have said '50 coins' & then mentioned that players' characters would probably use gold, while most regular people would use silver at best.
