I said a good teenager might run 10.7 and you have found a list of teenagers (I don't know how old they are) that can do just that. Very few people sprint after they leave college but if they spent time becoming stronger and more physically mature then 10.7 would be quite achievable - even a good highschool runner can run that time.
My original point being that people can run this fast and that if they do they would only be a few percent slower than the pinnacle of the sport. Even from the list you shared there most of the runners in those state finals ran 10.7 or better. Imagine an olympic final that had extra lanes for the fastest teenagers from Californian highschools. We would see a horde of 60kg teenagers that could finish the race less than a second (<10.7s) behind the fastest man in the world (9.80s in the previous olympics) over a 100m race.
20 out of 40M people doesn't seem like a horde to me. In fact, it seems like the chances of any teeneger running 10.7 is vanishingly small, around the chances of winning the lottery.
So going back to your statement, it's really more like saying, "One in a million teenagers is able to run within 10% as fast as the fastest man in the world. But that 10% barrier is incredibly difficult or almost impossible to cross."
