I don’t know what the situation is for commercial games — I don’t know if there’s a marketplace like that — but I do remember someone setting up some repository for free/Creative Commons assets a while back.

It’s not highly-structured in the sense that someone can upload, say, a model in Format X and someone else can upload a patch against that model or something like that with improvements and changes, though. Like, it’s not quite a “GitHub of assets”.
I haven’t looked at it over time, but I also don’t think that we’ve had an explosion in inter-compatible assets there. Like, it’s not like a community forms around a particular collection of chibi-style sprite artwork at a particular resolution, and then lots of libre games use those assets, the way RPGMaker or something has collections of compatible commercial assets.
I’m sure that there must be some sort of commercial asset marketplace out there, probably a number, though I don’t know if any span all game asset types or if they permit easily republishing modifications. I know that I’ve occasionally stumbled across a website or two that have individuals sell 3D models.

I mean, whatever. It looks like up until the current AI buildout, most came from Mexico. If China tries taking over Taiwan, that could produce a situation where Taiwanese chip capacity is damaged during a conflict, and that could be a real problem for the US, but I seriously doubt that there’s a realistic scenario where Mexican output dramatically implodes.
It does mention that some of those are just effectively-but-not-classified-as reimports from Taiwan — probably importing components and doing just enough work in Mexico to make it count as a transformative change — but the numbers are a lot lower, so it can’t all be that:
