This achievement is not retroactive. You will need to win 10 hands with Full House (two pairs and three of a kind). The best way to get this is to always play every hand. If you get a pair or better on the flop, check/call. If you have two pairs or better on the turn, check/call. When you get a full house, don't raise the bet because the computer might fold and could mean you won't get credit for it. The chances of getting a Full Houses varies but you will probably have this while going for the Poker Fan achievement.
