I am just curious if my license as a student does not allow the us of CASS. Other posts on the community say that you need a "US Insight Data" license??
That is correct. The "US Insight Data" is the new name for the spatial data package. This is a separate download and requires a specific license to use, which I don't believe is included in the student license.
It might be worthwhile to reach out to the Alteryx For Good program (which provides the student licenses) and double check this information.
