Linear algebra isn’t a prerequisite for learning data structures and algorithms. Though you typically do find linear algebra to be part of the lower division computer science curriculum at most colleges. I would recommend you take a course in it, I argue it expands one’s problem-solving mental models.

I certainly agree. However, if OP is simply referring to learning the typical algorithms presented in an undergraduate CS course, then linear algebra isn't a strict prerequisite.
