How do remote control things work? How can I press the up lever on a controller and make an RC car move across the room?

what you have as a RC remote it is basically a radio. Think like it sends some sounds through this radio frequency and the logic at the RC just listens for that. When you hold down forward key, remote just sends some beeping sounds meaning “forward” command for the other side(which is the RC car)
TV remotes work a bit different, only with infared light. Just like you can’t hear radio signals, you can’t see infared light. There’s an infared LED at the tv remote and one light sensor at the TV. when you press a button at the tv remote, it blinks the led accordingly and tv picks that up. Think that one like a morse code.
These are the 2 most basic remote things. There are more complex remotes like A/C remotes who also show temperature at the remote. But they are not so much different at the basic level.
