I don't know what the second line means, but suspect systemd is
complaining (?). I assume the third line is a consequence of the
second.

Then I rebooted and looked for Samba:

If you don't use a DC(nmbd.service) you should check the status of
'smbd' and not 'samba'.
$ systemctl status smbd

Yes, that looks better.
If you still want to use samba.service you could try:
$ cd /lib/systemd/system && ln -sf smbd.service samba.service
I don't know if the above command has side effects though.
It would be nice if the package name and service name matched, but
"service smbd status" works and I don't know systemd, so I will leave it
alone.
It is the safest approach, but you should familiorize yourself with
Systemd! :)

Correction, 'ad-dc' is controled by the 'samba-ad-dc.service' and not

Ok.
But what do the error messages mean?
You can use samba in two ways:
- Active directory domain controller (1)
- Samba daemons and related services (smbd,nmbd,winbind) (2)
You either use one or the other.
Debian provides both possibilities that is why 'samba-ad-dc' is also
included but masked (see (3) for what "mask"ed means).
If you have a "small domain" and want to use the DC as a file server you
will still need winbind (not recommended by the samba team) (1).
Failed to preset unit: Unit file
/etc/systemd/system/samba-ad-dc.service is masked.
/usr/bin/deb-systemd-helper: error: systemctl preset failed on
samba-ad-dc.service: No such file or director
The perl script 'deb-systemd-helper' (4) is responsible for the error
because the 'samba-ad-dc.service' is masked, but as far as I can tell,
everything is working properly though.
Should I file a bug report against the samba package?
What I would do is to get in touch with the script
"author"/maintainer(4) to confirm whether it is a bug or if the error
message could be improved.
