Is mining anonymous?

i bring up this question because here What is credit mining? i did not find an answer.
As i understood, mining (the term) means: mining anonymous.
But in the graphics linked in that topic it says “big goal”. So what does that mean?
Is mining now already anonymous or is this the goal to achieve, and therefore at the moment it is NOT anonymous?

@tribler55 Credit (or Token) mining is anonymous by default set to use 1 hop anonymity.

But it is possible to make them non-anonymous if you explicitly override the anonymous setting by selecting zero hops from context (right click) menu in credit mining downloads.
