If you genuinely don't know much maths, maybe Eugenia Cheng's "How to Bake Pi" also published as "Cakes, Custard and Category Theory"
I enjoyed it, it's not a text, there are no exercises. Popular overview of the subject, including a first half that mentions category theory only in passing.
Brave to even attempt such a book and I thought she pulled it off rather well. I hope we hear more from her and others mathematicians are similarly inspired.
