That's a tall order. I doubt it, but I imagine Zelda and Mario will surprised a lot of sales figures this gen.
They have the benefit of being games that will never really become outdated on the Switch. Whether your buying the Switch March 2017 or March 2022, chances are you will be eyeing these two games as must haves. I mean 2 97's. I don't know the circumstances for why someone is buying a Switch in 2022, maybe its for some new game they really like releasing then. Maybe they finally old enough to purchase themselves. Maybe parents finally got them it. Ect.
Doesn't really matter the reason. When one gets the system, they will look at the library and Zelda/Mario will definitely still be stand outs just for their critical reception alone. They may pass cause they don't like that kind of game, but anyone with a switch will be recommended those two games for its entire lifetime.
