Many places, including SV, have companies that give that title even to those who haven't studied CS or math formally.
But besides that, I see a deeper motivation in the article. The author says
"My dream is to learn the statistics, probability, and linear algebra needed to really understand machine learning and computer vision...I need a solid foundation so that I can truly understand what's going on: why something works, when it won’t work, and what to do differently if it doesn’t."
I contend that even many who have formally studied CS and math probably don't truly understand these math tools, that is, if they are using them in the first place. Intuition in math takes time to build up, and requires considerable mental effort.
