I think that if i manage to set up it up ill just use the bitcoin core as a cold wallet since its encrypted and anybody that would want to do any transaction would need the Trezor, right?
Right, encrypted or not.
The descriptors that you'll import only contain extended public keys (xpub), it can only derive its child public keys.
Your private keys stay in your Trezor.

One warning though: never export even a single private key from your hardware wallet (e.g.: manually derived from the seed phrase using tools)
Because almost all wallets are now using non-hardened derivation paths after the 'account_index' to be able to achieve watching-only HD wallets.
If even single private key and its parent's pair 'extended public key' are compromised, it could compromise all the child keys of its xprv parent.
