Yes/No. There's three-ways Uma Musume handles real life relationships.
>Soft Reference: Kitasan Black 'feeling' something familiar about Bakushin (their grand-father), or Scarlet Vodka being a massive Tachyon simp.
>Medium Reference: Rudolf being Teio's dad in all but name. Season 2 had so many dad moments that they might as well have just dropped the veil and said it.
>Hard Reference: The Mejiro's all have the same surname, so they kind of admit they're related but rarely elaborate beyond that.
The horses are canonically isekai'd from our world into being uma musume, so all the relations are still 'legitimate' in a spiritual sense (thus why they'll reference the relations). But they want to keep the cast 'pure' for the players so they won't make any of them real parents in this world.
