Also Tik Tok launched outside of China only in 2017, much too late for the supposed 11 to 15 year olds to turn 18 to 21 as implied by the GP's comment :-) The thing people miss about why TikTok (and WeChat for that matter) are so good is that they're born in the gladiatorial world of the largest and most competitive mobile app market in the world that is China. I know my marketers there work with not just douyin (the original Chinese app of TikTok) but also 4-5 other short video platforms. The pace of innovation in Mobile apps in China is something not matched anywhere else in the world.
