Answer

This sentence is a quotation attributed variously to Will Rogers (American humorist), Walt Whitman (American poet), and Dizzy Dean (baseball pitcher). It just means that an actual accomplishment stated as a matter of fact is not boasting. It's not modest, but Americans are not usually known for modesty.

Answer

this sentence is quite insulting.

Basically, someone has said that they have done something amazing, perhaps like be on the moon or see a beautiful waterful.  The person who said this sentence has made a 'comeback' where they feel that what they have done, because the person has done it, does not deserve to be bragged about.  To brag is to boast, to speak highly or yourself and your achievements.

I hope this helps! :)
