We have millions of cars, planes, rebar, jewelry, bullets, boats, phones, wires, etc. How is there still metal being made? Are we projected to run out anytime soon?

There is an entire planet under our feet. You might think it’s only one planet, but the damn thing is big. There is enough planet for each and every person in the world to have 139 cubic kilometers of it. If you took your part of the planet and had it as a cube the side length would be 5.2km, and much of that volume is various metals. How much of that available metal are you personally actually using and how much of it is still in the ground? We are quite literally just scratching the surface.
