The longer someone stays, the more people will want to customize their model.

The average beginning player will just copy other people's avatars. In fact, they have to until they get uploading rights after a few hours.
Then they tend to acquire one from Booth, or maybe import an MMD model. (It used to be more MMD before Booth became a thing, now it's the other way around because Booth avatars are designed to be retard-proof to upload.)
Following that, they've stuck around for a while already and will customize their avatars heavily, often starting with frankensteining parts from other models, sometimes eventually making accessories from scratch.

In rare cases, people will make avatars from scratch or commission someone to make them.

Note that a large population of VRC always tends to be just visiting people and questlets, though they don't matter at all to the experience of players who play for longer than a few hours because the visitors and questlets tend to stick to public lobbies while long-term players tend to stick friends+ instances. (At least in EU and NA. SEA has more publics.)
