I can see that - it's like musicians that don't rate musicians who can't play piano.
But - I guess I've seen a few counter-examples in coding - e.g. I used to know a mainframe guy who had arthritic pain. He coded very slowly indeed, but it flowed out of him flawlessly.... So I tend not to have that bias.
If I met someone who wanted to get into programming, I certainly wouldn't say "practice your typing" - I'd say, "read these books".
