Fame
Your only shot at fame is to deal a feature table at a televised poker tournament. People won't know your name but they'll see your face.
Or at least your hands.
So who knows—perhaps you'll run into someone at the supermarket who looks over while you're picking out a frozen chicken and says, "Hey—I know those fingers!"
If fame really is what you're in Vegas to pursue, it might be a good idea to really perfect those card handling skills. If you can learn a few tricks, there's always an outside shot that you can make it as a magician. At least the odds of you getting famous are better than those of your customers going home with any cash.
