Why does my simulation code not adding to the variables? [closed]

I'm very new to coding and I made this rock, paper, scissors game in python. The singleplayer and multiplayer works fine but the "simulation" mode doesn't give any results for player one wins or player 2 wins. The output would be:

Player 1 won 0 times. Player 2 won 0 times. There were x amount of ties.

There shouldn't be 0 wins for both player one and two.

There shouldn't be 0 wins for both player one and two.
