Yes.  The desktop machine is providing services (loosely put, I/O
device - screen, keyboard, mouse - access) to the machine where clients
(X clients, that is) are running.  (Also, a minor note: to quote the X
docs, "it's a window system called X, not a system called X Windows".)

Worse than that.  "Modern" clients don't draw characters as bitmaps.
They do antialiasing and subpixel rendering and suchlike.  (My terminal
emulator, which does have a mode in which it uses a client-side font,
gets usable speed out of it by (a) not doing stuff that, like
antialiasing, requires more than 1bpp and B9) pushing the character
glyphs to the server _once_, to pixmaps, then drawing them by teling
the server to copy from the pixmaps.)
