Z, You raise some good points and to some degree you are right. The low resolution maps are inaccurate in minor specific details.
Here is accurate information about who lived where in the various districts of the area which later became Israel and the Occupied territories.
Land ownership by district

Here is a map.
Notice the green majorities?
Jews mostly lived in urban areas and didn't own much rural land. Nor did many Jews have communal rights to communal lands. (But some did) So land ownership tends to skew division against Jews.
The following table gives the demographics of each of the 16 districts of the Mandate.

More accurate than land ownership, but non-Jews were still a clear majority.
By 1945 Jews were a slim majority in some cities and towns, but by district they were still a minority in all but one. If the UN held a referedum and used the first past the poll method to determine which districts should make up Israel, Israel would have been Jaffa.
If the UN would have let all Palestinians vote on whether or not to create a Jewish state, the overwhelming majority would have voted against. Nearly all Palestinians (Jews and Muslims) were against it. Only some of the recent Jewish immigrants were in favor of stealing land from Palestinians. But that minority was heavily armed and supported by powerful international Zionists:

Dividing up land between Jews and non-Jews in Jordan was a lot easier.
There were no Jews living in what became Jordan in 1945. To be fair, what percent of the land should 0% of the population get Z?
In 1945, more Jews lived in Japan than in what became Jordan.
