Correct - I didn't study a STEM subject, but I've done ok for myself despite that. I think there's a world of difference between "I want to study acting and I'll end up successful like Brad Pitt" and "Hmm, my cousin is in marketing, and seems to have created a great career there, I should talk to them about that." Anecdotes about people you don't know, and career stories you don't fully understand aren't helpful, but frankly I don't think massive data sets on how much the average graduate earns within two years of graduation (for example) are all that helpful either, except as a broad way to compare yourself. It's such a large number of people, you don't really anything particularly useful at an individual level (even though there are plenty of good uses for data like that).
