I am in the same position, except I have had a humble bundle subscription from the very beginning.

Of games I have specifically paid money for, I believe I have played 100% of them.

It's probably the wrong interpretation to say a lot of people are making the decision to buy an individual game and then not playing it. Although I know people who do that, even with physical boardgames, they usually have the intention to play but life gets in the way.

That's a completely different scenario to myself where they just accumulate without me noticing. A number of times I have read a retrospective of a game and wondered if I owned a copy already. I usually get around a 50% hit rate on those.
