Well, not quite. The concept is that the X-server services the requests
from the X-clients (to draw stuff on its display, report events, etc).
But you are definitely right about which machine it runs on.
At first glance, this _is_ a bit confusing because usually it is the
client that has the interface to the user, but with X, the server also
has one (and usually client-user-interaction is also redirected through
the server).
