What you say is true of the statistical majority of those who call themselves Jews. There are, however, Jews of the Book or Jews of the Old Testament who are not Talmudists.
Judaism as such, is a man made construct. It is not a religion proper but more akin to a cult.
There are indeed some who practice the approximation of the ancient old Testament religion, (but they are few, a true remnant).
Those who call themselves Jews just because they do not follow the Talmud, does not automatically make them Israelites. The are simply members of this cult who do not hold the authority of the Rabbis to be supreme but still indulge in erroneous interpretation of the scriptures and Judaic practices just as their Talmudic brothers do.
They are still part of Judaism which is not a part of the old religion.
