My original TXID was exchanged for the exchange price and the BTC was redirected to another wallet that was not mine. Please help I don’t understand

So we began withdrawing from Beton Line (casino/poker platform) and retracted it to the wallet of the cash app. I’ve done this hundreds of times between the two and have never had any problems before. I know that the Cash app has received a transaction, but it is pending and has not been confirmed. Time passed and when I checked the blockchain it says that the original TXID has been replaced by RBF. In the first TXID I showed the transaction amount and the correct cash app wallet address as output, but in the new “exchange” TXID my wallet is not listed as output, nor is it listed the transaction amount. New amount, new address. From what I found online, isn’t this impossible only by hackers who have seed phrases for the sender platform or the sender’s wallet? Or is this likely a problem with the cache app? Thank you for not really understanding any help. Edit: Also, it has been confirmed more than 25 times on the blockchain and is not pending.
