Yes, non-profits is a superset of "charitable non-profits". The IRS puts all 501(c)(3) organizations under the same filing framework. Hospitals and universities are in there alongside food banks and shelters. Breaking them out by NTEE code gives a more granular picture is a great idea.

501(c)(3) is just one of 29 types of non profits defined by the IRS. Many non-profits aren’t charities and some of them can even distribute profits.

501(c)(7) IE non profit social club for example could be just about anything from knitting circle to a S&M sex club. Have that club buy property and then at some point in the future sell that property at a profit which is then distributed to those members.
