This helped me a lot. I could remove the count of unread messages when it's
equal to 0, with the following:

--8<---------------cut here---------------start------------->8---
      (defun gnus-user-format-function-y (headers)
        "return string representation for unread articles"
         (propertize (if (= (string-to-number gnus-tmp-number-of-unread) 0)
                         "        "
                       (concat gnus-tmp-number-of-unread " Unread"))
                     'face 'my/unread-face))

      ;; format of the group buffer
      (setq gnus-group-line-format (concat "%7{%M%}"
                                           "%8{%m%}"
                                           "%P "
                                           "%(%-39,39g%) "
                                           "%6{%3U Unseen%} + "
                                           "%5{%10uy%} "
                                           "%7{%3T Ticked%} < "
                                           "%6t Total Items"
                                           "\n"))
--8<---------------cut here---------------end--------------->8---

Though, I would like to do the same with the counts of unseen or ticked
messages, but the variable `gnus-tmp-number-of-unread' does not exist. Any
idea on how to do such?

Thanks a lot for the help you provided me with!

Best regards,
  Seb
