That's "back of the envelope" calculations, with some big assumptions made about the mining operation how it's powered, who is powering it, etc. To modify a past block, an attacker would have to redo the proof-of-work of that block and all blocks after it and then surpass the work of the honest nodes. Requiring a proof of work to provide the signature for the blockchain was Satoshi Nakamoto's key innovation.
