Question about 3d model licences

So I want to find one (ONE) 3d model of some car that I can use in my game which in future I might consider to sell ,and I found this 3d website http://tf3dm.com/ but when I search for 3d models on the right side its said “for personal use only” ,on some models it also says “non comercial only” + " for personal use" and some its just " for personal use".So can I use this models if I wanna sell my game (talking about those models without “for noncemrical use” adds and with only “for personal use” adds) ,does “for personal use” means I can use them as part of my projects and then sell my project as a whole (like unity assets) or I cant use them in anyway?

There are also other websites like http://www.turbosquid.com with free models but I dont know am I alowed to use them in my project?

If you sell your project / game to someone ,you are making money → its commercial usage.

If you give your project to someone or share it but not sell it → non commercial usage.

If you just use the models inside of your private projects and not share or sell it → for personal use

(Im not a lawyer but that how i see it.)

In any case you cant sell the original files in there original form(that includes the unity project files).
