Yes, and "alive" is quite stretching it. Even if Norris wins every point still available in the last 3 race weekends, Verstappen only needs 24 points to secure the title. He could finish 6th three times to secure the title. Even if Verstappen doesn't get a single point in the last races, Norris needs to finish second every race and sprint and then get at least two more points through fastest laps or a win. There is still some mathematical chance but in reality over.

Yep. There's two races and a sprint left after this one, so it's technically possible for Max to score 0 each time and for Norris to score 25+25+8+1+1 by winning both races, sprint, and fastest lap for a total of 60 points. (maybe 61, does Sprint have a fastest lap?) The current gap is 62 points, so Norris only needs to close the gap slightly this race to make it ok.

Of course, we're talking about it being "technically possible". Realistically, he was struggling to catch up even before last race where Max won and increased his lead.
