In a sense I have the same experience as you. I regularly use little bits of the theory we studied in college, except that I only understand that theory because it was re-taught to me by more experienced programmers at my internships/jobs. Nothing I learned in college really stuck because it wasn't taught with any context or application. Computer science was part of the engineering department at my school, so I think it's reasonable for me to expect at least some understanding of how the theory relates to real-world situations.
