Resolution YES means that the new state is either a member state of the UN, or that they are defined as a “state party” (in the same way that collective Palestine is currently) as according to this article (ignoring plagiarism or incorrect edits )

Palestine refers to only current Gaza and the [occupied] West Bank in the context of this question
@JoshuaWilkes This is as it says. All of the above would count, yes, if they are recognised as independent states that were not already recognised as such, but it would also count if an entirely new state were to emerge anywhere within Gaza and the West Bank
Clarification here that based on how I phrased the question, “Palestine” refers to Gaza and the occupied West Bank, but looking for opinions from those who bid as originally I envisioned this as a state anywhere in British mandatory Palestine’s borders. If people are willing I will change the description to clarify “mandatory Palestine” in that case, but otherwise this means Gaza and the occupied West Bank
