There is a difference between general education and those software certifications. I have masters in physics and had never really studied software formally. Having studies in University I believe had set me up for life, very grateful. However I've switched from science to being a programmer fairly quickly for financial reasons. I've never taken any software course and in my about 40 years long stint I was never asked about any software certification. What did happen instead 2 or 3 times when I was getting some consulting gigs was that the client would try to have me pass some IQ / Aptitude / Whatever else test. I already have a reputation for delivering solutions and whole bunch of nicest references. So I just apologized and walked away. Not playing these kindergarden games.
