Yes and no.Dialga isn't rare in the sense that there is an opportunity to catch a Dialga in every copy of Pokemon Diamond, and even players of Pokemon Platinum or Pearl can trade to get a Dialga. There is only one in a game of Pokemon Diamond, but it isn't rare since there is one in every Pokemon Diamond.Dialga is rare because it is only available in Pokemon Diamond, and there is only one Dialga, and only one chance to catch it. Plus, it is classified as a legendary Pokemon, and all legendary Pokemon are rare.
