The function 'kevin-spamassassin' sends the message to spamc. There is
no need for teaching; it should work 'out of the box'. Well, ... :-)

Random thoughts:

1. Just to be sure: you did evaluate the code above, for instance by
   reloading your .gnus.el or restarting Gnus?

2. Old (seen) mails, even if unread, will by default not be split, only
   incoming messages.

3. If splitting works and you did not have a group 'spam', then this
   group will be created, but you need to subscribe to it: in the
   *Group* buffer, press '^', then go to your server, press enter, to
   have all groups listed.

4. You can try if kevin-spamassassin works: go to a 'good' message and
   in the article-buffer, press 'C-u g', which should show the article
   in raw form. Enter 'M-: (kevin-spamassassin)'. If the function works
   and the message is not spam, you should see 'nil' in the echo area at
   the bottom. Now go to a spam message and do the same; you should
   see 'spam' in the echo area.
