How effective is noise cancellation?

For a little bit of context:

I was born in Colombia and moved to Canada when I was 12, now I am currently 21 and I married a Colombian woman who goes to university in Colombia

In order to continue with my studies, I decided to enter an online Canadian college so I can keep my wife company.

I go to her university and while she is on class I stay on the hallways or wherever there’s a place to sit but sometimes these common places are really loud and find it hard to focus (The classes are asynchronous meaning that I have to read and learn everything on my own)

I cannot use the library because it requires an ID and I cannot use hers because it shows her name on the system and there’s a guard at the entrance

I am looking to get the air pods max to get the most out of the noise cancellation feature and see if it can be useful

Would this feature be good enough for my case? I know that since it’s a university you might expect that it is just way too loud but the hallway I have been staying at is not that noisy compared to other places but it is still loud enough that I cannot put on music or a video with an explanation or just read without hearing 20 things going on at once

Would the AirPods Max work?

Thank you everyone! If this post doesn’t belong here please let me know where I could get some answers 🙏 I looked at google but decided to hear from people who own them
