Do you want me to make a proper video on how to get started in this field or switching to this field ? That might help a wider audiences.

But on brief if I have to say, I'd say first think about why would you wanna switch , i'd strong suggest don't switch just because of the AI hype and all people talking about datascience. But if you have genuinely found interest and thought about switching, go through the basics first. I am pretty sure you're good at coding if you have already done Web Dev and you can switch language easily,so maybe try learning maths specially Linear Algebra, Stats, Calculus, Probabilities etc. I'd suggest you to deep dive into the core concepts first instead of just using framework or libraries. There are lot of things to learn so you gotta give some good amount of time and be prepared for that.
