yes, because everything is ran in it's own little bubble, and udon is it's own vm. 
a lot of player communication is somewhat peered in vrchat, (user audio for example). You actually upload to other users in a multicast kind of way, I sometimes push like 8mbit up plus in the beta in maps with 40+ users who are inside the new networked IK beta and audio falloff bubble. 
Vrchat even with it's animations triggers and actions system is low latency enough to handle something like a beat saber clone that other users can watch in the same room up to a certain point, but udon does that even better. With a map tick rate around 17ms (which is what overwatch uses) with udon you could build a "favor the shooter" system on par with pavlov, easy. VRChat doesn't use PUN anymore, they outgrew it.
