I didn't say it's the sum total anywhere nor did I imply that in any way. I also didn't say it doesn't represent some aspect of human knowledge.

In set notation, what I am saying in above comments is

    ({data} ∪ {knowledge}) \ ({data} ∩ {knowledge}) ≠ ∅

while you are simply assuming (without a good reason) that I am saying

    {data} ∩ {knowledge} = ∅

If you look up the chain with the example of singing a Queen song, maybe that will help you better understand the angle that that commenter and I share about the differences between data and knowledge.
