They SEEM like one, simplistic descriptive term that should be self-explanatory, when in reality Types have a broader "cloud" of what exactly they mean, or can mean. A Water Type can be that Type because it summons/controls water to attack. Or because it's a being made of pure water. Or because it lives in the water. Or because the thing it's based on contains a water-based pun (which is something all the Types do). Or even just because the creature has properties which are merely similar to water. Or some combination like that.
So the Dragon Type is really the.....dragon Type, but think about the broader aspect of what that may mean, and how that can be applied.
First and foremost it denotes the modern, well-understood European and Asian dragons we're so familiar with. Great, fire-breathing reptiles which hold tremendous power, and represent the tip-top of the food chain. Look deeper into it however, and you'll find that what qualifies as a "dragon" has historically been very loose at times.
A snake, bird or fish can be called a "dragon" They're not real animals, so it doesn't really mean anything. Kind of like how fairies have a popular modern Tinkerbell-like image, when really an ACTUAL fairy can apply to a host of different stuff.
Goodra fits because it's from a vaguely dragonish creature, and is a Pseudo, meaning it's more powerful than most Pokémon. And no Goodra isn't fearsome, and neither is Altaria or Dragonite, but they each have their own separate justifications for the Type. You can have a weak, docile Dragon. Not literally every Dragon needs to exude raw power, but almost all of them do and it is a common trend. It's supposed to be the Type that is extremely powerful but also extremely difficult to tame or control, so it's a hard-journey big-rewards sort of deal. All Dragon Types do seem to have some sort of powerful deep blue mystical life energy though.
