I think that’s a misconception. Data structures and Algorithms are at the core of “programming”. For example: Elements of Programming Interviews in Python.
A Common-Sense Guide to Data Structures and Algorithms (amazon.com reviews) uses JavaScript, Python, and Ruby to cover some of the basics.
Personally I think those languages are less than ideal for the task - something in the vein of HtDP2e would be more useful - but most people are more utilitarian in their choice of programming languages and I’m not aware that there is any commercial viability to Racket right now.
I just don’t like web development, but if I had to choose, back end development is the place I want to end up.
Unfortunately there is the whole (mythical) fullstack developer thing going on - so in many cases there is some interaction with the web - so “web avoidance” is likely going to make matters more difficult for you. Mobile-first web apps are encroaching on native apps, Electron-based desktop GUIs, etc.
