I learned maths mostly by teachers at school writing on a whiteboard, university lecturers writing on a blackboard or projector, and to a lesser extent friends writing on pieces of paper.
There was a tiny supplement of textbook-reading at school and large supplement of printed-notes-reading at university.
I would guess only a tiny fraction learn exclusively via typed materials. If you have any kind of teacher, how could you? Nobody shows you how to rearrange an equation by live-typing latex.
