Yes you are right. That’s what you learn at good universities: all the core data structures and algorithms you can use to build whatever you want. However you don’t need to go to University to learn this. There are great books on algorithms and data structures you can read to learn it as well. Playing around with different algorithms/data structures in your own non-work code is a fun way to learn.
