LTSP clients can be set up as Thin (X or Similar Protcol served over
network only) Medium (where X terminal & some applications are run
locally but essentially most programs are hosted on the Server) or even
as thick clients (whereby the server just acts as a central repository
for resources).

However the original LTSP concept is one BIG server with lots of little
computers networked providing user access points to the BIG server.
Think the good old bad old days of the Mainframe. The clients where not
supposed to provide any computational power (beyond providing screen
rendering and keyboard / mouse capture and networking).

Over time the LTSP concept has become very blurred of course ......

Ironically the X-terminal protocol came about because (back then) the
X-terminal was  likely to be the most expensive piece of kit in the
machine room, since graphical screens and the processing necessary was
very expensive and very specialist (ie build it yourself) kit. So the
idea was that the X-terminal could be pointed at any one of a number of
machines when graphical output was necessary. In effect this was one
graphical terminal shared between many servers. Now LTSP is about one
server shared by many graphical terminals ......

Occasionally history likes to turn things on their head .......
