I know very little so please don’t mind a lot of stupid questions.

I want to do my masters in AI/ML but afraid that it will be difficult for me to understand. I am not a bright student and struggle with understanding maths a lot. how much maths does an average AI/ML person do in their job? what things I should keep in mind while learning AI/ML?
does whole AI/ML landscape has been taken over by LLMs? I have seen a lot of people complaining about CEOs shoving LLM every where instead of just a simple ML model.
what does AI/ML people do exactly? I mean what are their roles? does the most important task for an AI/ML person is to decide which model to use or is it preparing the data or understanding the requirements?


Unfortunately, the field is pretty brutal about just assuming you are fully caught up to everything in the field, or that you will read the references for a given statement. You often don’t need to know all the math, but at least have a general idea of what some concepts are. I’ve been part of ‘journal clubs’ for the past 5 years where the only really goal is to stay abreast of the changes going on so that a new paper doesn’t send me down a rabbit hole of reading a referenced paper, which also has unknown terms, and read those references, etcetcetera.
I’m not in a great position to give useful advice due to that. it might be a good approach to find a youtuber who gives a 20-30 minute review/summary of a single paper that looks interesting, and of the video makes sense, then try to read the paper, and if you get stuck, see if the YouTuber has a video on the concept that got you stuck.
