In one line

Bytes read off S3 per query. Query count barely matters, unless you buy provisioned capacity by the DPU-hour.

What gets missed

Partitioning and columnar formats are the whole game. DDL and failed queries are free, cancelled queries bill for what they already scanned, and each query rounds up to a 10 MB floor.
