wrong.

****

[jaju@tachyon jaju]$ file `which startx`
/usr/X11R6/bin/startx: Bourne shell script text
[jaju@tachyon jaju]$ file `which X`
/usr/X11R6/bin/X: symbolic link to Xwrapper
[jaju@tachyon jaju]$

*****

Xwrapper in turn (it's a suid program) execs /etc/X11/X file, which is
again a symbolic link to the actual binary (say, /usr/X11R6/bin/XF86_SVGA)

You can't directly execute /usr/X11R6/bin/XF86_SVGA (because you need root
perms to get control over the comp to start X windows). The Xwrapper file
does some checks and then passes control to the binary.
