The two people you mentioned were not titled royalty. Perhaps that clears up your mind.
Just a small example of the official title of the Queen of England: Elizabeth II, by the Grace of God, of the United Kingdom of Great Britain and Northern Ireland and of Her other Realms and Territories Queen, Head of the Commonwealth, Defender of the Faith
Full title of The Nizam of Hydrabad: Lieutenant-General His Exalted Highness Rustam-i-Dauran, Arustu-i-Zaman, Wal Mamaluk, Asaf Jah VIII, Muzaffar ul-Mamaluk, Nizam ul-Mulk, Nizam ud-Daula, Nawab Mir Barakat ‘Ali Khan Bahadur, Sipah Salar, Fath Jang, Faithful Ally of the British Government, Nizam of Hyderabad and Berar
So I think a bit of learning/research on your part need to be done before you say anything about anyone on social media. No offence. Just my 2 cents worth.
