I agree. But there's more to it though. There is male and there is female, but they are one in Christ.
There is the house of Israel and the house of Judah. In Christ the two are one:
Gal 3:28-29 "There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise."
The promise of the New Covenant is made to the house of Israel and the house of Judah (Jeremiah 31:31).
The house of Israel are collectively called "Ephraim" in prophetic scripture, and on his deathbed Jacob (Israel) told Joseph that his seed would become the fullness of the Gentiles (melo goyim in the Hebrew, which is translated as "a multitude of nations" in the English Bibles):
Gen 48:19 "And his father refused and said, I know, my son, I know. He also shall become a people, and he also shall be great, but truly his younger brother shall be greater than he is, and his seed shall become a multitude of nations."
Over 1,000 years later, and after the Israelites had taken possession of at least part of the promised land, and after Israel and Judah had split into two kingdoms called "the house of Israel and the house of Judah" , God said the following regarding the house of Israel/Ephraim:
Hos 1:5-9 "And it shall come to pass at that day, that I will break the bow of Israel, in the valley of Jezreel. And she conceived again, and bare a daughter.
And God said unto him, Call her name Loruhamah: for I will no more have mercy upon the house of Israel; but I will utterly take them away.
But I will have mercy upon the house of Judah, and will save them by the LORD their God, and will not save them by bow, nor by sword, nor by battle, by horses, nor by horsemen.
Now when she had weaned Loruhamah, she conceived, and bare a son. Then said God, Call his name Loammi: for all of you are not my people, and I will not be your God."
So God had mercy on the house of Judah at that time, but not on the house of Israel.
Yet immediately afterwards, the same prophecy says,
Hos 1:10-11 "Yet the number of the sons of Israel shall be as the sand of the sea, which cannot be measured nor numbered. And it shall be, in the place where it was said to them, You are not My people, there it shall be said to them, You are the sons of the living God. Then the sons of Judah and the sons of Israel shall be gathered together, and shall set over themselves one head, and they shall come up out of the land. For great shall be the day of Jezreel."
In its Biblical context, the above prophecy refers to "Ephraim"/the house of Israel - yet hundreds of years later, Paul applies it to those who believe in Christ:
Rom 9:22-26 "What if God, willing to show His wrath and to make His power known, endured with much long-suffering the vessels of wrath fitted to destruction; and that He might make known the riches of His glory on the vessels of mercy which He had before prepared to glory; whom He also called, not only us, of Jews, but also of the nations? As He also says in Hosea, "I will call those not My people, My people; and those not beloved, Beloved. And it shall be, in the place where it was said to them. "You are not My people; there they shall be called sons of the living God."
So there God had mercy again on the house of Israel, but this time, the vast majority of the house of Judah are broken off through unbelief - but in Christ, there is only one house, one Israel, comprised of all who believe in Christ, whether Jew or Gentile.
Then we get Paul's statement in Rom 11:25-33, which is a can of worms because either it means that the entire house of Judah will one day repent of their unbelief, and all the Jews of that generation will be grafted back into the Olive tree again (and that the rest have been spiritually wandering in the wilderness in unbelief and perishing in that wilderness), or it means only that God had mercy on the Gentiles who believe in Christ through the genetic seed's unbelief (the Jews who happen to be called "the house of Judah"), and nothing more.
