That is probably the common case. That is similar to degrees with majors in software engineering, computer engineering, etc… There are also people working in technical jobs in computing who have mainly self-educated their CS knowledge (having either earned a degree in an unrelated field, including humanities, social studies, or arts, or not earned a degree at all).
Also, job ad “requirements” are often expectations or wish list items on the part of the recruiter rather than hard requirements.
