Judaism is a religion. Jews are from all over the place. Almost none from Palestine.
"Judaism" sometimes refers to the religion, but many Jews are not religious. Jews are a group of people from Judea, hence its historical name. Some dispersion to other regions doesn't change where a group of people is from.
