I always enjoy these "how many gas stations are there in Chicago?" back-of-the-envelopers. My first thought was maybe a small city of 50000 might be served by 10 ATMs more-or-less. Scaling up to 7B people worldwide my first guess would be 7B/5K ~ 1.5M . Maybe even less to account for my unrealistic first-world-everywhere methodology. So my guess is wrong too.
