But it doesn't leave them without perspective.
The tiered school model of Germany sorts you into one of three tiers based on your abilities with the age of 10, which gets even more specific over the years after that.
Only people finishing from the highest tier can go to a theoretical university, people from the tier below can at maximum go to a university of applied sciences, and people from the lowest tier can only go to a trade school.
Obviously, these tiers have different lengths of education (5 years, 6 years, 8 years), and you can always switch up a tier if you believe you can do it, but most people take what's recommended for them.
And this is necessary.
We, as a society, have to accept that some people won't be able to study maths. Or computer science.
For some people, applied sciences, or even a more technical job might be more ideal.
The solution isn't to get everyone into college, but to accept the fact that not everyone can do so, and to also value the job the manual workers are doing.
There is this nice advertisement campaign from 2014 from the German association of craftsmen, "What would the world be without craftsmen?": https://youtu.be/YfgqIWwxk2g
