Well, Paypal has been around for longer and works across the world, which explains some of it.
But I question the accuracy of these stats - I would expect to see SEPA wires and direct debit being significant everywhere, Multibanco and MBWay[0] in Portugal, TWINT in Switzerland, giropay in Germany, etc
Also, even if they are accurate, they rank Joe's homemade soap shop the same as a major retailer, and don't consider how many customers actually use each payment method.
