One of the first things you learn in Stats class:

An "error" is normally-distributed. Over a large enough sample size (n > 100, typically) an actual error will trend toward zero in aggregate, and very reliably will be within 1SD. Over even larger sample sizes this becomes even more-true. Confidence range shrinks as sample size rises, in other words.

An "error" that always goes one way, especially when the sample size is huge (e.g. n > 10,000) is not an error -- it is fraud.
