That does not show you can distinguish < 20 ms latency. Latency is specifically the time between you taking an action and getting a result. I would doubt that most people would be able to tell the difference between 8ms and 16ms of latency between a button and light or speaker.
There are two other ways scrolling on a 60Hz vs 120Hz phone would allow you to tell the difference: the increased smoothness of the scroll (not related to latency at all) and how far the content lags behind your finger. The content lagging behind where you initially touched does allow you to experience the latency, but that is more of a visual only experience than a temporal one.

It's well regarded that the reduction of 11ms in latency is very much noticeable. https://news.ycombinator.com/item?id=20091610 https://news.ycombinator.com/item?id=20091610
- ilyt 4y agoIn case of this particular interaction its just easy to notice because you have direct view of pen position and what it is drawing so any latency means the pen is dragging but there is nothing under it. It's different for where you don't have same senses for both. "Pressing" a key is feeling + sound but reaction is change in image, you don't see keyboard and screen at same time so it feels more tolerable.

It's not really more tolerable, unless you never experienced low latency here, and your brain is used to the effect of a key press being perceptually immediate.
