No, the person in question will only see the overall number of likes and dislikes that have been given to the post; they will not see any further details. Only in the event that you leave a remark on a video or a response to one of the already existing comments will the username be shown. On YouTube, the "like" and "dislike" buttons are anonymous in order to discourage "group-ism" and other forms of biassed voting.
