Default Re: P(x) vs. P(y |x)

Thank you! however I still need the author or another one clarify the sentence more... when he says "gauging how well we learned", I think he speaks about the test set.

We also know that we should avoid sampling bias. Then in my opinion P(x) is used in training set to make it unbiased, not?

and we know any distribution we used in training set we should use in test set, then P(x) is used in the test set too.

However I still don't know if we know P(x) or not, is it known?!
