After the Castilian Succession War was won by Isabella, her rival Juana remained in exile in Portugal where she took the votes so that she could never claim the throne again. And after that, there never any more threats to Isabella's throne by Juana's supporters, who basically wanted on her throne only because she was a child uninterested in politics and they could govern in her place. Is there a reason why Henry VII couldn't do the same?

Since he was the son of Elizabeth of York, the eldest surviving child of Edward IV, while the Poles and the De la Poles descend from Edward's younger siblings, and the Courtenays from Elizabeth's younger sister.

They even skipped Helaena's own coronation with Aegon.
