This does not seem to include transactions on the Bitcoin Lightning network which are transaction that are handled offchain so they are not included in blocks. I don't have the exact number of lightning transaction ocurring but it is the Bitcoin Core developers' plan that the scaling to thousand of transactions per second will and should take place on the lightning network (this is where they differ from their competitor Bitcoin Cash which is aiming for bigger blocks and onchain scaling). Bitcoin is still a technology in its infancy ten years after being started.
