It depends on what exactly is meant by "comments" and what is meant by "deleted".

If "comments" refers to posts in Discussions or on the new message walls used by UCP wikis, then only admins can see them.

If "comments" is referring to article comments, blog comments, Forum posts, or legacy message wall posts, then it depends on what is meant by "deleted". These posts have a edit drop-down menu that appears when you hover over them. This menu contains a "remove" option which will hide the post(s). However, individual posts can still be viewed directly; usually via the post's user's contributions page. However, it is possible for admins to delete the pages that the posts are stored on. If this is what happened, then only admins can view them.

If "comments" refers to what a user typed on a talk page or wiki-style forum page, then it again depends on what it meant by "deleted". If the entire conversation page was deleted, then only admins can see it. However, if just a particular comment was removed, then it can still be viewed by viewing an older version of the page.
