Sorry, but once again you ignore the fact Judas was lost and became the son of perdition and was not mentioned in Revelation.
John 17:12–13 (KJV 1900) — 12 While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled. 13 And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.
And even the apostles believed a new 12th had to be selected.
Acts 1:15–26 (LEB) — 15 And in those days Peter stood up in the midst of the brothers (and it was a crowd of persons of about one hundred twenty at the same place) and said, 16 “Men and brothers, it was necessary that the scripture be fulfilled, which the Holy Spirit proclaimed beforehand through the mouth of David concerning Judas, who became a guide to those who arrested Jesus, 17 because he was counted among us and received a share in this ministry.” 18 (Now this man acquired a field for the wages of his wickedness, and falling headlong, he burst open in the middle and all his intestines spilled out. 19 And it became known to all who live in Jerusalem, so that that field was called in their own language “Akeldama,” that is, “Field of Blood.”) 20 “For it is written in the book of Psalms, ‘Let his residence become deserted, and let there be no one to live in it,’ and, ‘Let another person take his position.’ 21 Therefore it is necessary for one of the men who have accompanied us during all the time in which the Lord Jesus went in and went out among us, 22 beginning from the baptism of John until the day on which he was taken up from us—one of these men must become a witness of his resurrection together with us.” 23 And they proposed two men, Joseph called Barsabbas (who was called Justus) and Matthias. 24 And they prayed and said, “You, Lord, who know the hearts of all, show clearly which one of these two you have chosen 25 to take the place in this ministry and apostleship from which Judas turned aside to depart to his own place.” 26 And they cast lots for them, and the lot fell on Matthias, and he was added to serve with the eleven apostles.
Judas had lost his position
You are simply assuming what your theology requires while ignoring scripture.
Further quoting
John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which ||taketh away the sin of the world. .
Removes your denial of gentile omission.
World does not mean Jews
You cannot even support your view with the verse you quote.
