"White" is a skin colour, otherwise categorized as "race", which technically doesn't really exist anyways.
All that really exists is a diverse range of genetic differences, however, all humans can 100% interbreed without any issues.
To my understanding, Jew refers to both an ethnic group and a religion, so it can be confusing, but the ethnic group definitely can be referred to as a race (which going by most the common dictionary definitions of race generally includes geographic and ethnic grouping. I looked it up prior to my earlier comment to be sure).
It is possible to be non-religious or practice another religion and be ethnically Jewish, and it's possible to be another ethnicity and convert to Judaism.
