But, see, I can easily believe there are lots of jobs out there looking for computer science degrees that are not computer science. Simply because, as you put it, it has a reputation for being "hard".
None of what you've described is evidence of their being a significant computer science field though, just that computer science graduates have a decent (but not all that much higher than a generic STEM degree) of getting a job.
Again, if you want to demonstrate demands for computer scientists rather, than, say, code monkeys with computer science degrees (because its an easy place to grab people who might be willing to be halfway decent code-monkeys), your numbers don't bear that out.
Also, I think I should make clear - at least in the US, we generally don't consider people with computer science degrees to be computer scientists, similar to how those with engineering degrees or psychology undergrad degrees are not necessarily engineers or psychologists. Being a computer scientist requires one to actually engage in computer science. I was simply wondering how many computer scientists there are actually working in your country, and what the demand is for actual computer science jobs.\
Because if all it guarantees you is "a job, any job" within a freakin' year and a half? That's not much of promise, and sounds more like a waste of money for four years time. I'm pretty sure I can manage to find "a" job given 5 and a half years no matter where I go, and without having to pay for Uni.
