I believe myself and others have interpreted "delete from dashboard" as "Hide" since the dashboard is just easy access to the course. Especially when it was followed with " I don't want to see them there everyday" as this sounds like they don't want them gone, they just don't want to see them everyday.
Are you using the free for teachers version of Canvas or does your school have a Canvas account? Either way, if you have the permissions to delete a course, open the course, and click on "Settings", you will then see options on the right side of the screen and one is to "Delete this course"

If you are part of a school that has Canvas, they may have the ability to delete courses turned off and you would need to contact your Canvas admin to then delete it.
