I am following a tutorial at https://developers.arcgis.com/python/guide/part2-data-io-reading-data/
When I use optional parameters from the from_featureclass() method to refine return results, I don't get a subset of the dataset. The full dataset has 3886 rows x 50 columns. It does not matter if I specify the fields parameter or SQL query or where clause, it always return the full dataset:

Any recommendations?
