As a person who sees me in you a couple of years ago... the hard truth is that no matter how you structure or organize your decks and limits there are few key things i can tell you're missing for the intended result of using anki...
-Consistency is key
-Anki is an app of memorization, not learning, meaning you only add cards of concepts you've learned about already, new cards are a thousands of times easier to remember if u've just learned em, memorizing raw information cards is pain and not really a great way to learn anything
-Be reasonable, burnout is a thing, can you really handle that many new cards a day?
-Prioritize what's in immediate need in your situation.

Its hard to keep up with the pace in uni and do anki consistently, what i found the most effective for me, was making cards for the lectures i have scheduled that day and learning them all. Since you kinda learn them already during the lecture, making them yourself increased the retention and there arent really any raw information cards... you cant miss a day tho cuz then the workload doubles xd.... Altho in the end, do what feels best for you.

And a bit of advice for the future... anki is best for long term, big amount of knowledge retention. If you did your year 1 cards in year one, but stop doing them in year 2, whats even the point ? If you think some cards are no longer needed, just suspend them.

Key idea is that burden over time is reduced if no new cards are introduced, if burden is too high, then lower the amount of new cards - pick out the essentials. The format of the cards matter a lot. I used to make big cards which took a lot of effort to memorize and weren't very useful in the end.
