Two quick things I can recommend without hesitation, which focus on an intuitive understanding of concepts:

1. Essence of Linear Algebra mini-series - https://m.youtube.com/watch?v=kjBOesZCoqc

2. Better Explained website - https://betterexplained.com

YouTube has a lot of high quality math content, it definitely helped through university. It's also worth mentioning the Stanford U courses.

The main takeaway I have for you is learn the concepts intuitively first, then spend the time to play around with them on paper until they sink in. Some things will be easy, some will be frustrating, much like programming you will walk away from a frustrating problem and have an epiphany while doing something completely different.

All the best and have fun!

My two cents are whenever something seems hard/impossible/infuriating/etc, take a break then seek dofferent sources on the material. A lot of times I have been hung up on something only to find that things make much more sense when approaching it from a different viewpoint. :)

No matter what I'm learning, I always refer to at least 3 different sources for any concept.

Absolutely! Not having to hit your head against a wall helps prevent burnout as well as just plain being more effective

That’s how I got to grips with trigonometry... I tried to understand why sine, cosine, tangent, cotangent, secant and close can’t we’re named like they were... then I found a bunch of stuff on the unit circle. Never looked back!
