I have no idea what it is that you are comparing or where you pulled those numbers from. The systems are not the same and we have a lot more than "universities" for higher education, such as Fachhochschulen and Hochschulen.
Overall, statistics says the number is 55% for the share of youth starting higher education in Germany: https://de.statista.com/statistik/daten/studie/72005/umfrage...
We also have what "Facharbeiter" for most non-higher education professions, which take 2-3.5 years. https://www.bmbf.de/bmbf/en/education/the-german-vocational-...
There is some discussion that there are now too many in the higher education track and too few in the vocational training track. We have too few "Facharbeiter" and "Meister" for a lot of important professions for the practical work.
Personally, having done both tracks - in 1992 I obtained what would now probably be called "mechatronics engineer" after three years of training in a school and a huge chemical fiber plant for the practical on.the-job parts. Afterwards I studied CS and half of business administration. I think almost two thirds of youth every year going to higher education is way too much. Again, we have this vocational training, if there was nothing and Bachelor degrees count both as higher education and are used in place of where Germany uses our vocational training system - again, 2 to 3.5 years! - than it makes sense to get at least a Bachelor. But here in Germany I think we actually could use shifting some of those 55% into the other track.
If you get such a vocational training degree, e.g. "Facharbeiter", you are already pretty well educated and qualified. If you add a "Meister" on top of that after getting some work experience you are on a path to really good earnings and don't have to hide at all from comparisons with top engineering degree holders. Those people would not show up at all in your comparison, because you don't have that system.
