No, they’re not.
However Zionism was created and developed in Europe and supported by European powers, and the first Zionist waves of immigration to Palestine came from Europe, and the first Zionist colony in Palestine (Rishon Le Zion) was established by Jews from Europe, and during its foundation and early years Zionism disregarded Mizrahi Jews and put Ashkenazi Jews on top of them.
Zionism has been inherently an anti-oriental, ethnocratic, and a European ideology.
While it’s true that Ashkenazi, Mizrahi, and Sephardi Jews all benefit from Zionism today, but it’s still an ethnocratic and anti-oriental ideology.
Look at all of Israel’s key leaders for example, all of Israel’s prime ministers and most presidents were all decedents of immigrants from Europe (Only one or maybe two presidents out of 10 were not, but all 12 Israeli PMs were of Jewish European lineage)
although the majority in Israel is Mizrahi.
