That isn't how the math works out for an ISP. You can serve on the order of 50k customers on a 20gbit/sec uplink.

Not when you’re promising them each gigabit speeds, though. Which many ISPs do now days.

On average, end users use about the same amount of bandwidth regardless of what speed plan they are on. Then planning is based on average and peak bandwidth

Usually not a promise, usually “best effort”.
