In Pakistan Urdu is the qaumi zabaam, the national language. But it is only the madari zaban of the 20 million or so Urdu speakers in Pakistan and about a hundred million in India.
On the Pothahari question, the language the Mirpuris speak is called Potohari. There is no such thing as a Mirpuri language.
