This just isn’t true with regard to F3 to F2 and promotion to F1.The year-end results and standings of European junior racing formulas are 90% irrelevant to determining the drivers that get promoted to higher auto racing series.
The French did this with Ocon, Gasly, Le clerc
The British recently did this Russel, Norris and Albon.
That’s 6 drivers from 20 , new and all were successful in promotion formulas. Stroll and Verstappen being your examples, with Verstappen being the talent of his time.
Your point just doesn’t stand.
Auto racing has always been about money.
