> Attentive CS graduates have a structured pool of information to draw from

Yes, but a self-taught Developer also has their own pool of information to draw from. That could be prior experience, but it can also overlap with the CS graduates' pool of information.

You don't need to take a DSA class to learn DSA. There is a wealth of information out there for self-taught developers to learn these kinds of things. From textbooks to YouTube videos, it is all readily available for anyone.

Self-taught does not mean you need to invent everything from first principles.
