Short answer

Ads Data Hub (ADH) is Google's cloud-based clean room for analyzing Google ads and YouTube event data alongside an advertiser's first-party data in BigQuery. Queries run under privacy checks that return only aggregated results, so advertisers can measure reach, overlap and conversion paths without accessing user-level Google data.
