We have no evidence that that is true, however it is widely speculated and believed to be so.

The speculation for that particular number is trivially falsified: It's based on assumption that all unmoved coins in the first year were mined by the system's creator (no justification is provided for this assumption).

And it is false, many other people mined during that time and lost keys (myself included).
