That used to be the case, but modern game engines like Unity make it easy to plop out an switch-capable version. The hardware is similar enough to a normal PC that it’s a matter of just turning the graphics down (way, way down). It certainly wasn’t a majority at the start but now more than half of new AAA releases have a Switch version.
That said, buying a switch to play AAA games is not ideal. I find the graphics compromises too great, myself. Indie games (only certain genres like platforming), visual novels and Nintendo-first-party games are what I find the switch excels at.
