Yes, that's the principle of why air wants to "move into the engine", but the engine is working like a pump too. The downward stroke of the piston with the intake valve open creates a pull on the air into the cylinder. The rings on the piston are just as important to filling the cylinder with air as it is to the compression of the air.
