Actually one of the reasons password manages are recommended is that entering passwords is never as fast as typing normal words so it's easier to shoulder surf.

It has to do with mental grouping [0]. Words aren't a bag of letters, their order has a particular meaning. The mental overhead of "tbwvpcrwx" is 9 letters, while "WrtCdEvrydy" is, for me, 5 things: "w" "r" "t" "cd" "evrydy" (and I assume based on the capitalization, 3 things for you).
With regular use, your mind creates a mapping of "thing" to "keypresses". As long as a password remains a 9-thing bag of characters in your head, those 9 things will be slower to type than a 3-thing set of letters. But if you can create mental meaning from them, your password-typing speed will increase to where it's indistinguishable from normal words.

(Quick edit: "WrtCdEvrydy" just dropped to "3 things" for me right after posting, I now have "Wrt" in my head as the fake-word "wirt".)
