No not all are saved.
Yes God became a Man and died as a Man for all Mankind, but not all Mankind want to accept this.
Hence why Jesus said this to a Religious Jewish master.
Jhn 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Jhn 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Jhn 3:7 Marvel not that I said unto thee, Ye must be born again.
