Want reality? Bitpay and Coinbase process about 90% of payments and their numbers total about $5m a day. Paypal does close to half a billion dollars everyday.
You're comparing only commerce numbers. They are comparing numbers based on one thing: "online funds transfers of any kind". The ability to move money for any reason, friction-less-ly. Paypal is restricted to commerce. Bitcoin can do commerce and much, much more. So its a little bit of a twist, but its a relevant comparison still. However if you only look at b2c sales, then yes, Bitcoin is nowhere near PayPal.
