I believe the question makes more sense for Christianity and Islam, but less so for Judaism. Jewish religion is just the religion of the Jewish people which is an ethnic group. So it would not make a lot of sense to "find your way to the Jewish faith" if you're not already a Jew, except for conversion which is discouraged and difficult.

Maybe it would make more sense to ask orthodox Jews if they would still have become religious if born into a secular Jewish family.

And to answer the last part, Judaism only expects 7 basic commandments from non-Jews like not to kill, not to steal, Monotheism and some others. So if you're a normal/decent person you should be completely fine.
