Is Sony responsible for the PS4's great sales, or are Nintendo/Microsoft?

Why would Nintendo's failures have anything to do with PS4's success?

If we're playing tennis, it's pretty freaking easy for me to win if you keep serving the ball out of bounds or into the net. 

Nintendo repeatedly shoots themselves in the foot, competing against them in the console space is easy. 

They have completely different audiences. It's like they're playing on different courts.
