A good post from fanverse:
"I have a theory about Mythical Zoans that suggests that Awakening is what "evolves" them. Luffy's is a Human Human Fruit, right? But he doesn't become this Sun God until he awakens. What if the same was true for Kaidou and Marco?
Maybe Marco's Devil Fruit only allowed him to transform into a bird until he unlocked its Awakening, which turned him into a phoenix instead. Kaidou's Devil Fruit would have only allowed him to transform into a fish until he unlocked its Awakening, which turned him into a dragon instead. "
So Marco and Kaido are already awakened and got some extra passive abilities, in Kaido's case it's weather control or having elemental attacks and in Marco's case, it's the logia properties with high level regeneration. And on top of their passive abilities, they have one final awakened form - like Monster Point or the Jailer Beasts - skyrocking all of their best abilities on absurd levels.
