PayPal is widely supported online but I doubt they are far, far ahead in the real world, which I think is what people mean by "mobile" wallet.
Between Apple Pay, Samsung Pay, and Android Pay (which I believe recently got rebranded as just Google Pay), Apple Pay is ahead in userbase numbers by a considerable margin — perhaps not as much now as a year ago, but I doubt it was overtaken.
