When I download a 25GB game I care about throughput for the download to a certain extent that is probably mainly ISP bound rather than local system bound. I don't care if the download takes 10 or 11 minutes as long as I can still use my system with zero delays meanwhile. And whether it takes 11 minutes of 3 hours depends on my ISP mostly. But being responsive to me while it downloads is local latency bound.
Exactly, lots of different things.
When I alt-tab I care about latency.
When I ssh I care about latency.

The Youtube example you have makes sense, sure.
