the pubkey exposed in a bolt11 lightning invoice never receives any money (it is only used for communication, specifically for signing your invoice and some messages on the p2p communication network) and does not expose your balance
also, anyone who scans your lightning invoice and sends money to you does not learn what address received the money (or rather, they don't learn what address *would* receive the money if the transaction went to chain). They only learn your node's *communication* pubkey, they don't learn where the money actually went per the blockchain's consensus rules.
by contrast, in monero, anyone who scans your monero public address and sends money to you learns exactly what address received the money and they can provably map that "stealth" address to your public address. This is part of how many monero users get caught, e.g. it is how chainalysis learned what transactions to investigate in the following video where they show how they caught a Columbian drug lord:
