I have met those people to, but none of those people have ever had a csv file to run queries on.

Analysis has a lot of meanings. Getting basic facts (there are N rows that X) and selecting subsets of data are realistic analysis non technical people might do on csv files.

And I want to be clear that parsing a csv file with sqlite or MySQL is much more complex than learning “SELECT .. FROM .. WHERE” (with no joins!) when there is a tool like OPs that magically does the “parsing”.
