I was curious and looked up the same thing. This is indeed referring to the Romani people. I’m assuming the number here comes from this Wikipedia page: https://en.wikipedia.org/wiki/Romani_diaspora#Population_by_country
Although the Romani people coming from Egypt is a popular misconception, there are apparently a large number of itinerant people whose ancestors came from the Indian subcontinent living within Egypt today, more than in any other country. After some digging, it appears that these people in Egypt are mostly the Dom or Domari people. They were for a long time considered a subgroup of the Romani because both groups are itinerant and originally came from India, but apparently recent research shows that these two groups are unrelated and just have similar stories, speaking different Indo-Aryan languages and leaving India at different times for different reasons. I guess the Wikipedia page (or whatever source KoljiVriVoda used) hasn’t been updated to reflect this yet.
