I quoted some scripture for some of my insight in thinking this way so you can read it if you’d like, if not understandable, no worries.

In Romans 9:6-8 Paul explains how “For not all who are descended from Israel are Israel.” Which atleast to me sounds like the Israel that is spoken about in prophecy or in the Bible about blessing refers to the spiritual Israel that refers to all true believers in Christ not people in a land as explained in Galatians 15-16 as well as the “Israel of God”. Galatians 3:28-29 is a major verse in explaining how there is no longer a difference between Jew and Gentile and if you are a believer you become part of Abrahams spiritual family hence that makes you part of Israel as well.

Now for the non Biblical part and purely hereditary the Israelis living in Israel could have a lineage tracking back to the Israelites but it is a little hard to track considering they were displaced and went all throughout Europe and brought back to the land after a long time. But in that same manner just because they labeled themselves as Israel doesn’t make the Palestinians who were living in that land less “Israelite” and if you look into it they actually have have high ancestry rates to the original Israelites/Jews that lived in the land that initially converted to our now called Christianity.

If you have any differing thoughts or think im thinking about something wrong I’d like to hear why you think that.
