A bit simplified but yeah. In the industry I think it's commonly referred to as "cleaning up the topology" or "simplifying the topology" where "topology" is the structure of the mesh essentially. You'd put the scan/model through something like this: https://sketchfab.com/blogs/community/retopologise-3d-scans-...
> is this true with top spec machines too?
Games frequently feature 100s (sometimes 1000s) of models at the same time, so the optimization of each model is important. Take a look at the launch of Cities Skylines 2 for an example of a game that launched without properly optimized 3D models, the performance was absolutely abysmal because the human/resident models were way more detailed than justified for a city simulation game.
