If you restrict it, then it isn’t public. I’m not saying that encrypted group chats are useless. But if it is public and anyone can join anyway, then encryption adds no secrecy.
The secret chats feature isn’t between anyone I believe, it’s between two people. But I don’t actually know for certain because I’ve not looked into it beyond a cursory googling.
That said, you’d be correct in that just like any service out there, the moment you let random people join there’s no level of encryption that can keep your secrets secret.
There is no point in encrypting a public group chat since anyone can join and decrypt it anyway.
It works well in Matrix, and you can restrict who joins on that platform.
