[|Human|] Behind Delta tables is the data stored in Parquet file formats?
[|AI|] Yes, they are parquet.  Delta API is a protocol and the layer manages the individual parquet files as if they were a larger table.  If BQ can consume from the Delta protocol it could work but I would not suggest reading the files inside of a Delta table as just a parquet table - there would likely be too many stale files
