Wrong. Yes, typing speed does not matter when counting up lines of code. Code programmers however are not just code monkeys. They write documentation and comments, communicate with peers and potentially users, take notes on their own thoght processes when pondering on the best solutions for hard problems, etc. On all of these point and many more, typing speed matters. People who can type and type fast(-ish) communicate more expressively, document more comprehensively, make less mistakes when spelling, etc.

So yes, typing skill matters.
