Also, if you look at the earlier parts of the video you'll note they're talking about competitive powerlifters and the sacrifices they have to make etc.
For general purposes even Rip says that you don't need to be over 20% bf for SS. He puts a ball park target of 15% in the clarification article. Should OP gain 10 or 20 lbs as his lifts keep going up, yes. Should he strive to weigh 200lbs ? only if he's squatting more than 4 plates or grows another few inches (which he very well may at his age).
