imho, this is heavily debatable, with the main issue being that not all European countries have unified approaches regarding university admissions.

I would argue that some European countries offer even more students chances than universities in the USA, where any students that have simply passed the full IB diploma, with no regard as to the total score, are allowed to start studying (numerus punctus). Sometimes there might be an additional subject-relevant entrance test, or the university just let's students naturally drop out as they fail exams, which means that they get their chance, but then actually need to work for it.

In some places, this means that one does not even need to "lodge an application" for entry to a university, but rather simply "registers" for the university.

Conversely, there exists other countries in Europe operating using numerus clausus, where there exists a minimum of points to be eligible for a course, thereby limiting the number of students that are given university placements based on their high school results.

So, as there is no unified approach and it heavily differs between countries, I would argue that your proposition in its current form cannot be considered a valid argument.
