At 16 your just starting out and at that young age everyone has a different starting point. Some people are bigger looking but not as strong, some are smaller and explosive. It depends alot on genetics where you start out.
Where you end up is a different story, that all depends on how hard you work. your lifts are a solid starting point at 16 (I don’t know where you lift that there are alot of people not benching 1 plate and squatting atleast 2 for reps) so keep working hard, eating, and reading on this site and more size and strength will come.
And search for creatine in the articles section of this site, there is a lot of talking about them and loading. Then make your own educated decision on what you want to do. Or load this time and don’t next time adn see which works better.
Good luck going foward and remember your still young your main (physical) focus should be on eating alot and lifting alot.
