Can't find decent assets anywhere or badly made

I tried to look on all available sites like turbosquid or evermotion and other sites. I also don’t want to learn any 3d modeling because Im really bad at it. I want to download particular assets that I need or packs then deleting unrelevant. Please Im looking for a site that can help me make open world game and it will be similar to Gta 5 or Watch dogs 2 or maybe even Skyrim.
