It's a rare example of English being simpler than other languages, so I'm curious if it's hard for a new speaker to keep the nouns straight without the extra clues.
The nouns still are gendered. Only the article is gender-neutral.
Tarzan is a man. He lives in the jungle.
Jane is a woman. She is visiting Africa.
The elephant is a non-named animal. It eats fruits and leaves.
If you really want to know a confusing issue about the English language, just look at the pronunciation of words. It is more or less rule-free, and all over the place. Don't believe me? Try to read the poem "The Chaos" aloud. Even most native speakers need several attempts.
