You haven't specified in which way this is too advanced for you.
Still, I'll take a stab at recommending some other resources.
1: Practical Deep Learning by fast.ai - a (free) hands on course that's designed to get you to making something useful as quickly as possible.
2: Neural Networks Zero to Hero from Andrej Karpathy - A Series of Youtube Lectures that requires only basic python knowledge and takes you all the way up to a simplified implementation of the tech inside gpt models.
3: Neural Networks from Scratch by Sentdex. A book that's explicitly written to teach you the basics. Doesn't cover stuff like Transformers and other advanced concepts, but really takes its time with the basics.
Take a look at all three of them. They all have a different teaching style and I'd guess that at least one of them will gel with you.
