But it doesn't average out. The 5ms player is continuosly 4ms behind the other player. As above poster explained - the times add up. So you have 200ms + one to five ms. If server tick is as little as 5ms the problem is even worse as in that case player A will with exact same reactions get a faster tick in 4 out of 5 times. I don't know how often it matters, but I'd expect top player to have pretty similar reaction times. So let's say 2 opponents are both between 200 and 220 ms reaction time - then constantly having 4ms more for one player definitely sounds like it will have an effect.

edit: Or in other words - it depends on how often the reaction of the opponents is with the 4ms difference. That certainly depends on the game and the players.

Most server ticks are nowhere near 5ms. Quake 3 ran on 20-30 tick, CS:S/CS:GO runs on 33 by default and up to 66 if you run on high quality servers. 100 tick was somewhat common in CS:S. Some really expensive servers claimed 500 tick but I never bought it. Either way no one's client would update that fast.

Furthermore, if you watch pro matches, you'll quickly realize their skill has nothing to do with having the fastest reaction time. Once you get to a certain skill level, it all comes down to game knowledge. Having a consistent 4ms advantage is absolutely negligible.

I just did go with the 5ms because you mentioned those in your previous post...
