Who is more famous Mario or Usain Bolt?

Answer 1

Mario is definitely more famous.

the explanation lies in the fact that Mario is a classic game. So naturally, kids back then (when the game had been created) are now adults and even kids now play Mario and they know the game very well. So, mario is not only famous among the adults of today who used to play the game as kids but also today's kids.

But Usain Bolt is an athlete and kids generally don't fancy such real-life sports. They prefer digital games or Video Games. So, Mario is definitely more famous than Usain Bolt.
