Did the cost estimate calculator provide an inaccurate estimate?

Estimate query costs

BigQuery provides various methods to estimate cost:

Use the query dry run option to estimate costs before running a query using the on-demand pricing model. Calculate the number of bytes processed by various types of query. Get the monthly cost based on projected usage by using the Google Cloud Pricing Calculator.

When I use the BQ interface, it estimates the bytes for each query in real time before I run it, does that turn off if the query is too big? I guess that isn't directly a cost estimate, but if I saw hundreds of TB I'd think twice before hitting "Run"...
