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 honestly dont know if this is sarcasm or not.
