Even for certain applications, 50ms is quite a lot. When using MIDI devices and playing piano over the computer, I certainly notice anything above 20ms.
We may be slow to react to sudden events, but we are very good at noticing the lag for predictive events (keyboard typing, piano playing, ...).
Martin Molin of the Wintergatan fame recently posted some experiments regarding latency on his YouTube channel[0]. From watching those videos it becomes quite obvious that your statement is definitely correct.
Yeah this rule of thumb was for low fidelity things like hand radio buttons.

It does make sense in my lay person’s understanding that the chain of eye -> brain -> hand for reactive events would be slower than brain —> eye + hand for proactive events.
