Why Can The Aging Mirage 2000 Destroy The Modern F16V In Taiwanese Military Exercises?

The Taiwanese Air Force conducted military drills this year to improve its combat capabilities. The exercises took place from October 30th to November 3rd and comprised several types of air-to-air, air-to-sea, and air-to-ground engagements. The goal was to assess the Air Force's annual readiness achievements. F16V BLOCK20, Mirage 2000-5, and IDF fighter jets were among the models involved.
Interestingly, four Mirage jets engaged in battle with four F16V fighters in a similar drill last year. Despite losing one Mirage aircraft, the Mirage pilots effectively eliminated all four F-16V jets. Why did the Taiwanese Air Force's air-to-air battle have such results? Is it due to the pilots' abilities, or is the Mirage 2000-5 actually superior against the F16V?
