I think someone who knows those dishes like the back of their hand would make significantly better sushi than me. On the other hand, I'm willing to bet that someone who just makes burgers probably can make sushi about as well as I could.

Would you expect the best Sushi chefs in the world to be competitive in a professional environment to make French cuisine? My bet is no, they focused their entire career on sushi. Similarly, a professional chef who knows how to make these two dishes really well would not be able to compete with professional sushi chefs without actual training in that specific discipline.
