You're still missing the point.
When we're talking about the elite WT Pros, they're _ALL_ in the top 1% (maybe less, top 0.5%). All of them.
So while the jump from 96% to 97% may be large, you're still pretty far from inking a WT Pro contract.
Further, as much as I love CyclingAnalytics, I've been a subscriber for a very long time, I doubt many WT Pros use it. So what you're looking at is probably 99% amateur racers.
This graphic from 2014 for American Football/NFL is likely very true for cycling as well. We have much lower numbers, so percentages might be slightly better, but breaking into the WT peloton is probably just as hard.
