In most cases, this difference is largely irrelevant, since when you perform a Google search, it doesn’t matter to you whether it says “About 10,400,000 results” or it says “10,415,027 results” – you’re still clicking on the first handful of links and going about your business. As an example, if we execute the following query, which aggregates the total number of DISTINCT authors, publishers, and titles from all books in the gdelt-bq:hathitrustbooks dataset between 1920 and 1929, we will not get exact results: The DISTINCT quantities it returned can be seen below: As mentioned above, by default, the approximation threshold for DISTINCT queries is set to 1000, but by including the second numeric parameter (n) in the COUNT(DISTINCT [field], n) function call, we can increase this threshold, forcing BigQuery to return an exact count for any number at or below that threshold.
