I see what you're reading, but I genuinely do not recall the show with any Dothraki or Dany or anyone actually saying she was inheriting 100k Dothraki.
Later in that wiki:
"In the
A Song of Ice and Fire novels, the Dothraki are numerous and are divided into large hordes or
khalasars which range over vast areas.
Khal Drogo's
khalasar consists of 40,000 warriors and is said to be unusually large. "
Drogo had 40,000 and his khalasar was "unusually large"... so who the **** put 100k together and bent the knee to Dany?
It doesn't add up to me, nor did it appear she had 100k at the battle, that would be 10x the Dothraki as compared to the Unsullied... there's no way 100k of them were there, they would have dwarfed the entire army 3-4 times over.
