I think a huge part of Switch's success is coming from it being many people's only console since the PS3/360/Wii era
There's a big casual gaming audience who's interest and attention fluctuate sporadically with the wind. Switch was able to capture their attention. My ex flatmate for example got a Switch OLED, Mario Kart and Animal Crossing and he almost never touches it lol. But its a fun distraction once a blue moon. Still that is his sole gaming machine.
This is also why I'm a bit weary of anticipating that Switch 2 will replicate the OGs success. It will do 100m+ for sure. But there will be plenty of Switch users who will skip next gen because they are satisified with the occassional distraction their existing Switch brings them and will slowly work their way through its back catalogue
