Yes, but CSMA/CA reduces that to a point where it works fine unless the
channel is heavily loaded.

I never said that - of course they share the bandwidth, just like two
separate clients do.  Noone installs one separate access point for every
device they use (not only because you would run out of free channels quite
quick, even with 5/6GHz) - multiple devices connected to a single AP is a
standard, supported scenario. Even when one client does heavy up/downloads,
the others will notice a slowdown, but not the packet loss problems that
were the start of this thread.

How? Being close to each other, they can easily "see" when the channel is
busy and will not step over each other's foot. Contrary, widely spaced clients
lead to the "hidden station" problem where two stations each "see" the
access point, but not each other, and start to transmit at the same time.
