You make it sound like we're the typical fanboys and fangirls. WMY won WJTTC 2014 and 2015. SYS won WJTTC 2017 (IIRC, first and only try). They went dark for most of 2018, especially after WTTC 2018 (WMY even lost to FTW 1-3), all thanks to Hirano and Ito because CNT didn't want to take any chances. Yet it was because of them that SYS got the chance to play WTTC 2019 and stopped Ito in her tracks and then went on to win ATTC 2019. The consensus on Tieba is that it was Hirano and Ito that forced the old guards out. Even
LGL chewed CM out for "announcing" her era had arrived, reminding her how many World Titles were needed to play singles in previous Olympics.

what was SYS age in 2019?
15 years old?
After rereading your comment, I'm not sure if you are actually understanding what I'm trying to say about CNT example where players are over 18 years old before become close to a leader and really solidating the position in there 20s.
Out of my memory without googling. FZD is likely the youngest to get a front seat in WR and CNT at a very young age. and he still had 3 to 4 big brothers keeping him in line.
Update
In fact, to proof my point (with some quick check)
at age 16, FZD hit WR10, but had 6 CNT mens ahead of him.
Within 3 months, he become a WR5 and had 4 in front of him.
This is what I mean by aging naturally
