You shouldn't just blindly take the polls at face value, you also need to be thinking critically about them, theres a lot of ways to misrepresent data, a lot of issues that can crop up due to how the polls are conducted, etc. and when she took all of that into account, the polls suggested to her that it was going to be a much closer race than most of the media coverage was saying.
She was still a little surprised that Trump actually won, but it wasn't totally out of left field.
