Sampling may be used on unique metrics in Ads Manager, and the Ad Insights API. Unique metrics are metrics that refer to the number of unique people rather than the number of actions.

Most unique metrics also contain the word unique (ex, unique link clicks), which makes them easy to spot. Using sampling on these metrics allows our system to surface ad reporting metrics as quickly as possible. Sampling isn’t used on non-unique metrics like impressions or clicks. In the case of non-unique metrics, the metrics you’ll see are based on all of the data available, not just a sample.
