I honestly dont know if this is sarcasm or not.
Game engines like unreal engine and unity have huge prefab libraries that contain both free and paid models and people can share or sell their own prefabs too. The problem with those are that you cant just pick models willy nilly as it can make the game feel like patchwork quilt when every asset has little different art style. Also in bigger production games things like polygon counts start to matter a lot, so in some cases its easier to make assets from the ground up than start to fiddle with existing models.
Most bigger studios have pretty large internal libraries they can pull from. Like for example mountain lions in GTA V and Red dead redemption are almost identical. They even use the exactly same sound in both. And bears in Skyrim and Yao Guai in Fallout 4 have same skeleton and some of the animations are fully reused.

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, though. Like, it’s not quite a “GitHub of 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 it spans all game asset types or if it permits easily republishing modifications.
