It's not _that_ simple. This really depends on your video server software. Iff 
you
use a SFU then either Firefox will have to send more data (which is limited
by your upstream bandwidth which usually is much smaller than your downstream
bandwidth) our your other clients will get only one resolution/audio codec. But
that has little or nothing to do with latency. BTW, Firefox does have 
experimetal support
for Simulcast, you video solution just has to use it (many don't).
To the OP: there is an immanent latency in all network connections - packets 
need to
pass through switches and routers, and let's not forget the speed of electrical 
signals.
While one can get pretty low latency on local networks (Dante et al.) trying 
live jamming
over the internet is pretty much impossible.
