There is a very big difference. Noahide laws are for the non-Jews. Judaism is only for the Jews. Different laws; different standards.
What makes people want GOD is Love not Law...
According to the Jewish Bible (aka the Old Testament), God wanted specific people for himself, not the other way around.
SO why does GOD need any Gentiles at all?
Why doesn’t he just keep the Jews and destroy all the Gentiles?
