Because you're using ksh, not csh?

man ksh

Compare:

man csh

I am using csh:

$ whoami
user1
$ echo $SHELL
/usr/bin/csh
$ !!
su: !!: not found.
$ hostname
server1

If you say so. But then please explain why
your error message said "ksh: !1: not found".
Are my eyes failing me, or do I see a "k" in
there, and not a "c"?

This tells you nothing about the actual shell you are running. SHELL is set when you login but is not changed when you type something like ksh. These are the commands:

echo $0
ps -f

These will show what you are actually running.

Or "ps -fp $$".
Or if you are running a real shell, to get all of your trees:
UNIX95=EXTENDED_PS ps -H -fu $LOGNAME
