Does Piastri have a chance of winning the championship next year?

McLaren is obviously the best car this year and that's a trend likely to continue next year, so for both drivers this is their best opportunity to win a WDC. But mostly for Piastri because if Norris wins the championship it could lead to Piastri being second driver the following years similarly to Webber in RBR. So does Piastri have a realistic chance of winning the championship assuming McLaren keeps up their performance?

Edit: I'm not asking a Piastri vs Norris question, IMO neither of them are ready to be WDC yet. Piastri is still rough around the edges in pace, tyre management and especially qualifying and Norris is still making elementary mistakes
