May I ask why this person has such a low fee on uniswap?

Hi everyone, I am using eth for the first time and I heard that the fees are high. I saw this guy who bought $spell with 350eth but the trx fee is only $16.85.https://etherscan.io/tx/0xbda11d1031e08770ecedc1a9fa72a280097ddd829af594ae33c3f3b3786a59bf But I found on another website that his fee should be 1.05 eth.https://dappgrid.com/uniswap-fee-calculator/ Why is this?
