While there is no correlation between the Visa claim of 70k tps to people on the planet, there is also no correlation to the number of servers needed to process UDP packets.

The "Visa network" is more of a trusted collaboration between a small number of banks operating multi-step transactions than it is an OSI Layer 1 - 5 concern.
