There are tons of people in Germany that have jobs as software developers and network engineers without a university degree.
IT is such a broad subject that even if you studied Computer Science in a university for 10 years you wouldn't know half of it. Someone that doesn't have a degree but specialized in an area and has practical experience in it is potentially more useful for a company than the guy that has never worked in IT for more than a year and only studied the theory in a university.
At the end of the day a university degree is a piece of paper that enables you to get a few other academical titles. What matters is practical experience. Any instructor, trainer or HR manager will tell you this.
The whole reason some jobs want you to have a university degree is so that they can reduce the volume of unnecessary applications from people that likely wouldn't be cut for the job anyway. That doesn't prevent you from sending an application and taking initiative if you think you're good enough.
If we look past jobs then I can tell you that some of the most known IT companies in Germany don't even require a grade 13 graduation certificate but are satisfied with a grade 10 for their apprenticeships, at least for the network guys and oftentimes for the software developers.
