Display stars Only?

Sure, create a copy of the “post-ratings-control.php” template, put it in your child theme folder (create a child theme of your curremt theme, if you don’t have one active already), and edit it. To show only the stars, remove the meta block from the template.

This is the nice way.

To fast and ugly way is to hide that text with CSS:

.ratings .meta{ display: none; }
