When people pay fees for transactions most of that fee is burnt. Blocks have a fixed amount of rewards given to the validator that created them and the validators that attest it is valid. When more fees are being burnt than Ethereum issued in blocks it is deflationary. It is deflationary at ~16 Gwei and fees have been higher than this for a while now. Validators cost very little to run, they're usually NUCs that use 20w, the main cost is the Ethereum you have to stake.
