Where/how do I start?

So I am about to start studying computer engineering within a month, and I would like to start learning already about code, programming, AI, machine learning and all that related to software. The problem is that I have zero knowledge currently, and I don't know where to start / how to start. Which order should I follow, which sources should I try? There are teaching apps, stack overflow which I only took a glance so far, books, youtube courses… What do you suggest? Thank you in advance.
