This is mostly true but the three religions you mention aren’t parallel in this respect. Apostasy in Islam is (typically) defined as someone who leaves Islam after being born into a Muslim family or previously accepting Islam: https://en.wikipedia.org/wiki/Apostasy_in_Islam. So it’s not a race or ethnicity, but in a theological and practical sense people are “born Muslim.” Put differently, separation of ethnic group, language, and religion are less well-defined in many parts of the world than it is among people of European descent.
