As accurate as our knowledge of genetics, which is not very outside of the identified set of pathological genes associated with hereditary disorders.
Your genome is very complex and we don’t have a model of how every gene interacts with every other and how they’re affected by your environment. Geneticists are working on it, but it’s not here yet.
And remember that 23andMe, Ancestry, and most other services only sequence around 1% of your genome.
I'd guess it's much less accurate than that.
Part of genetics is pattern matching, and last time I checked I still can't find a model that can correctly solve hard Sudokus (well, assuming you don't pick a coding model that writes a Sudoku solver.. maybe some of them are trying to do genetics by doing correct algorithms), a trivial job if you write a program that is designed to do it.
