It was said that Morgana is older than Arthur, I think it was Katie McGrath who said that. Anyway, if the throne was really rightfully hers, Arthur would have resigned and not wrongfully claimed the throne. Obviously, Arthur's right to the throne has never ever been questioned by anyone. Moreover, Arthur was the son of both queen and king of Camelot whereas Morgana was the illegitimate daughter of the king only.

Emilia Fox is 38 years old and Bradley James is still 28. I doubt that a woman who is almost ten years older can play a character younger than Bradley James. Morgause is definitely older than both Morgana and Arthur. So no Great Purge and no ban of magic when she was born.
