Think about it.
If award tickets earned credit toward Million Miler status, by redeeming awards solely on UA, a member of a Star Alliance partner could earn lifetime Premier (1P) status without ever paying UA a penny.
OK. Admittedly, that would be a lot of awards!
But this is one of those "obvious" questions, former errors long ago (pre-1990) about crediting award tickets with mileage credit notwithstanding.
