My native language is Greek and it has grammatical genders. It's not a "problem" for native speakers because children soak nuanced details incredibly fast. You never hear kids have problems with it, only non native speakers, usually from the Anglosphere because the concept is absent from English thus unfamiliar.

English too has subtle grammar rules that after close inspection are surprisingly complex yet most native speakers don't realise they know them. A good example is the adjective order. https://www.theguardian.com/commentisfree/2016/sep/13/senten...
