Perhaps a way to clarify the errors in your logic (which is separate from evaluating the conclusion), is to go for something similar. If we compared training for indoor soccer to raining for FIFA-rules soccer we'd find those training exclusively for indoor soccer will probably perform poorly at FIFA soccer. Why? Different context they've trained for. Smaller field, can use walls (I think that's true for any wall bordering the playing area), and hard floors will all change the way the game is played. Similar toolsets, but used and trained differently.
