honestly as someone who just graduated (undergrad)...its not that simple.
people are doing pharmacy because you go in set to do Pharmacy/Healthcare so your degree is a hardscience degree or something else that's not super useful (bio, nutrition, chem, etc)
A lot of these students went to top universities yes, but without a more useful degree, it often doesn't matter.
I'll use myself as an example. My school is a top public school in the country. they're a top 10 program OVERALL in civil, chemical, petroleum, biomedical, electrical etc etc etc engineering. They're also top 10 in finance, accounting, marketing, management...and so on.
Sounds great right? Well guess what. All that does it make it hard to switch into those majors if you're a current student. So now you picked a major like Bio in high school, realized pharmacy isn't great in college but you can't do much about it. A degree in a hard science CAN be useful in many places but its hard to do something besides PhD/research or Healthcare. Medicine is too hard or long or competitive for some people and so they stick with pharmacy, hoping they'll make it.
Not to mention, a ton of students are doing the 2 years then pharm school right? Which means you apply summer of your freshman year...they don't know any better! You're basically still a high schooler at this time. I personally was in a similar boat but luckily I knew I really wanted to be physician and switched out. but others are left with their hands tied.
Now don't get me wrong. there are tons of people who go into pharmacy not knowing anything and get in bc the requirements are so low. But a lot of the "passionate" students are what i described and they don't have many options than to pray it works out
