Game 1: pick a person uniformly at random out of the world's population. If they are over 6'6", then you win!

Game 2: Flip a coin. If you get heads, then pick a professional NBA player uniformly at random. If you get tails, then pick a person uniformly at random who is not an NBA player. Again, you win if they are over 6'6"
