> the fact is that less people take the IIT-JEET (a couple of hundred thousand), than some of our exams here - like for law school and medical school

Do you have some source backing this up? A cursory search reveals that more than 850,000 applicants attempted the IIT-JEE exam in 2023. Total available college vacancies slightly more than 16,000. This number would be around 5000 for the OG IITs.

For US medical colleges, for 2022-2023 admission cycle, 22,712 of the 55,188 students who applied to medical school matriculated. Perhaps these numbers belongs to a specific US region?

I would say that attempting JEE is now more or less a cultural thing. 90% of the applicants (pardon the number out of thin air) sit the exam because that's just something you do after finishing school.
