Arab Race Superiority

So I will keep it short. I came across a man who said “Arab race is superior even if the individuals are not” and provided proof which made me search around because I only knew about the Hadiths concerning the individual matter.

Messenger of Allah ﷺ said in his last sermon that “All mankind is from Adam and Eve, an Arab has no superiority over a non-Arab nor a non-Arab has any superiority over an Arab; also a White has no superiority over a Black nor a Black has any superiority over a White except by piety and good action. Learn that every Muslim is a brother to every Muslim and that the Muslims constitute one brotherhood. Nothing shall be legitimate to a Muslim which belongs to a fellow Muslim unless it was given freely and willingly”

But the position of Ibn Uthaymeen رحمة الله عليه supports that guy’s argument. Shaykh said that no arab is superior to a non arab or the other way around except for Taqwa but he adds that the Arab race is better than others. Shaykh Uthaymeen’s position

The guy also gave some reference of Majmu al-fatawa which I couldn’t confirm because I have only read some parts of the book which are explained by Sheikh Saleh Al-Fawzan hifzullah.

So what makes the Arab race “better” since everyone is from Adam عَلَیهِ‌السَّلام?

I would use the word “privileged” for the Arabs since the Quran is in the Arabic and our last Prophet was an Arab & spoke Arabic but my knowledge doesn’t compare to Shaykh Uthaymeen, so anyone got an explanation?
