Those are just different translations in English, but the meaning remains the same, which is that it is the subject of the sentence that is sticking to something, adhering to something, being glued to something. It's not a transitive verb.
The transitive verb where the subject is sticking/gluing the object to something else is the hif'il form הדביק.
Because נדבק means to have something else stuck to you. The role of the subject of נדבק is equivalent to the role of the indirect object of דבק. Or in other case it's like a true passive, where דבק would be the middle voice.
