Champlin Park Fall League, so it was legitimate H.S. ballers, but obviously not very good competition for the Hopkins' players.
By the way, Paige introduces a protégé, Amaya Battle (great name) as her successor. She played for Hopkins last year as an eighth grader and will graduate in 2022. She is a 5'8" point guard and Paige presents her highlight film on Paige's Twitter page. As Sonofadomer said, the competition is suspect but there's no denying her form, and she has Paige for another 2 years to emulate.
