To answer your question above, as I said from the very start, he was not convicted of any criminal charge. He lost a defamation lawsuit, from in which, the jury had found there was an assault.
The differences are pretty significant. In this case he lost five million dollars. If it were a criminal case, he would have been found guilty, as you initially stated, he would be in jail, and permanently have a sexual assault conviction on his record.
The differences between a civil trial and a criminal trial are readily available in many a many a book. Read one.
