I grew up poor though and teaching myself coding moved be to earn more then I thought I'd ever earn without a college degree.
I knew about for loops almost a decade before I decided web dev would be my career, not just my hobby.
it's insane that you could get hired and not know how they work.
linked lists, sure. I still don't fully understand those lol, I was going for an associate's and that was in my c++ class but I've mostly only touched PHP, python, ruby, JavaScript... playing around with go and rust some as well, but I've never had to really think about linked lists, loops on the other hand is a daily thing.
hell, not knowing loops is like not knowing how to increment, like seriously, his to add 1 to an int.
Smh....
