OP has provided the right links but either misunderstood the text or phrased it very confusingly.

Ethereum's crowdsale supply was 72 million ETH. Of that 60 million were sold for BTC in the crowdsale. 6 million was given to the Ethereum Foundation and 6 million to early contributors (overall 20% of what was sold was created as a pre-mine).
Now Ethereum's supply is ~122 million, so the miners produced 50 millions new ETH.
Oh, I was a bit unclear there. The 9.9% was of the total money that was raised in the ICO (60m) and ended up being ~5.9m.
The total initial premine was 72m (~59% of today's supply).
I think someone more knowledgeable might provide a better breakdown of those funds, except that the article(s) linked covers it a lot better than my comment.
> Today it accounts for something like 59% of total supply. Make what you will of that.
Can you help me understand what exactly this means? Ethereum's supply has grown since the presale, so if anything the 9.9% should have gotten smaller since then.
