Yup. Equipments and tools aside, the BGA IC chip soldering / desoldering skills you've seen fast forwarded through the clip are some serious skills that take time to practices.
PS: This technique has been around since April 2015. A Youtube search yields roughly 8000 videos. I wouldn't be surprised that there are dozens or even hundreds [1] of this "repair shops" in Shenzhen's huaqiangbei or Beijing's Zhongguancun [2] electronics market.
There was even a similar video tutorial made by iFixit Vietnam;) [3]
