The scores come from the Chrome UX Report (CrUX) dataset which is a record of actual scores and from the HTTPArchive dataset comprised of lab measurements of the exact same sites in the CrUX dataset. The two dataset scores and measurements are combined to create the Core Web Vitals Technology Report.
