I believe they do. Often they will admit such in their books, statements to each other, their notes and sometimes even in their blogs. There was a link to one recently posted on here where the therapist was an absolute nightmare. I did not go to a therapist to be reprimanded or scolded or told how to be to satisfy the therapist. The therapist's thoughts don't worry me. They can think whatever they want. I don't want to know what they think, but that they think such things is not a problem for me. I find it a bigger problem that they try to sell themselves as not being judgmental rather than that they try not to openly act judgmental.
