Mario Kart and Pokémon sales are just on another level

Looking at the Switch sales, Mario Kart and Pokémon are absolutely overwhelming.
Maybe it's because everyone around me is an older guy, but no one I know plays Mario Kart or Pokémon... Who on earth is buying them in such high numbers? These seem like titles that kids or women would enjoy, but since the main consumer base for console games is mostly men in their 30s to 50s, I didn't think there would be many kids or women playing.
