All the saved are not Israel. Another fantasy of yours.
The first book in the Bible tells us who and what Israel is. See Genesis 32:28.
Genesis 32:28 Then the man said, “Your name will no longer be Jacob, but Israel, because you have struggled with God and with men and have overcome.”
Did you see that? The one who struggles with God and with men and overcomes…
And Jesus in the last book of the Bible confirms this message. See these scriptures in Revelation. Read what Jesus says about overcoming.
Revelation 2:7 He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give the right to eat from the tree of life, which is in the paradise of God.
Revelation 21:7 He who overcomes will inherit all this, and I will be his God and he will be my son.
And there is only one way a person can overcome this world, and that is through Jesus Christ our Savior.
1 John 5:5 Who is it that overcomes the world? Only he who believes that Jesus is the Son of God.
Therefore, who and what is Israel---Israel is people who overcome by faith in Jesus Christ.
Just as Jacob is called Israel by overcoming, we too are Israel by overcoming by faith in Jesus.
So are you able to become a son of God or not?
