Paket properties are not respected on the public internet, but organizations do make use of them internally. For public clouds who operate global networks, they can typically send video streams at low/mid priority all the way to "last mile" ISP by peering with so many networks and just running massive WANs internally. So they can get most of the benefits of prioritization, even though the internet doesn't support it.
