Are online personality tests a sham?

I'm pretty sure my results show a bias against white people because those niggas are nosy af, always calling 5-0 to report "suspicious behavior" just cuz a nigga tryna smoke a L in the local park.

Those things arent 100% accurate, but it does give you an idea of what type of person you are. My personality was ENFJ

These tests are bogus, Sort of reminds me how colleges' suggest unwary students to take low enrollment programs deemed relatively close to their personality test results, in hopes to keep the programs going for another academic year. As you mentioned, people's mood change frequently therefore initiating the difference in each test.
