Yes, sadly, your money is gone.
This is a very old scam method... create a watching only wallet for someone with X BTC in it, claim the user needs to deposit to "unlock" funds... wait until they deposit then simply move all the funds to another wallet.
The variation on this is to setup a wallet for someone on a service like blockchain.com and tell the user they need to log in and then change the password. Meanwhile, the thief has the 12 word recovery phrase already and can therefore restore the wallet, regardless of password being changed. Then simply wait for user to start using wallet and deposit funds, then steal them all having cloned the wallet using the 12 word recovery phrase.
The learning from this scam is that you should NEVER let anyone create a wallet for you... EVER!
