Netflix has appliances installed at exchange points that caches most of Netflix. Each appliance peers locally and serves the streams locally.
The inbound data stream to fill the cache of the appliance is rate limited and time limited - see https://openconnect.zendesk.com/hc/en-us/articles/3600356180... The actual inbound data to the appliance will be higher than the fill because not everything is cached.
The outbound stream from the appliance serves consumers. In New Zealand for example, Netflix has 40Gbps of connectivity to a peering exchange in Auckland. https://www.peeringdb.com/ix/97
So although total Netflix bandwidth to consumers is massive, it has little in common with the bandwidth you pay for at Amazon.
