I need help understanding an English Phrase

[Platapus]

Even though I am a native speaker, I still stumble over some English phrases.

What does "accept full responsibility" mean?

"I made an inexcusable mistake and accept full responsibility for my actions," Rice said

I have also heard politicians use this phrase.

I think the phrase "I accept full responsibility" means that we should not talk about it and that the person should continue to be rewarded by keeping their position.

I know that English is a tricky language and that an English phrase does not always mean what the individual words in the phrase mean. But I gets confused. So lemme see if I gots this straight

""I made an inexcusable mistake and accept full responsibility for my actions," Rice said" really means that he does not accept any responsibility and that his mistake (crime) should, in fact be excused and that he should be allowed to go back to the NFL and earn millions of dollars.

Am I getting this right?
