This is true. I loved my time doing Compsci in university and I feel I was probably more suited to doing that for career, but software jobs were plentiful and I still don't know where I would find a computer science job aside from a university
There are absolutely computer science jobs, but in general, a casual distinction would be what side of the research/implement line you fall (though in truth, it's probably more of a 2D graph than a hard line).
Building software is just one application of computer science
It's a bit like the difference between someone who is a psychologist helping people in therapy, and a psychologist who studies psychology in a lab. They require similar educations but they are very different professions
