The quota is for family reunion. Professionals don't need the quota, they can just apply for a visa.Original Post Deleted
60 spots out of 150 are reserved exclusively for children born on the Mainland to at least one HK parent. Quite frankly atrocious that they even need a quota spot, were they born anywhere else they'd be HK citizens automatically.
In 2019 there were 39060 arrivals under the quota, or 107 per day.
For 2020 the figures were: Q1: 95/day Q2: 18/day Q3: 38/day
