When graders are just/already assigned to all submissions, the interfaces shows

0 submissions are ready for grading, but have no grader assigned yet.

It would be better to show something like

30 submissions have a grader assigned. You can check the assigned graders on the submissions page (link)
There are 0 submissions left with no grader assigned.
