gpg symmetric encryption just derives a key from the password so theres no forward secrecy. Using bittorrent in particular opens you up to the risk of third parties getting ahold of your encrypted file and without forward secrecy the can attack the password offline which is typically much smaller that 256 bits. Using Magic Wormhole would seem to be far more secure than gpg and bittorrent since it has less risk of third party interception and uses SPAKE2 which has perfect forward secrecy. If I had to use bittorrent to transfer a sensitive file I would generating a random key and encrypt, then share the key over a different channel.
