And actually they still have a chance to compete for the title if Napoli throw away a lot of points.
I see it's impossible for Inter to catch Napoli, and it's also impossible for Napoli to just throw away this golden opportunity for them to become a scudetto, maybe Napoli can lose or draw in later matches but Inter must continue to win without also wasting points, and also other teams who are competing for the championship must suffer a drop in form which is why I say it is quite difficult for Inter to catch up.
Inter's current points are 30 while Napoli's points are 41 so the difference in points between the two reaches 11 points. with this huge difference, I see it will be difficult for Napoli to catch up. Napoli will not waste a golden opportunity to win the Scudetto this season, they have been fasting for a title for several years, this season must be their best achievement.
In this case what you said is true, but reflecting on the consistency of the clubs in Serie A like last season, for example, when Inter were far enough ahead with 8 points they could still lose and were immediately in 4th place at that time even though they eventually caught up again.
It is possible that something like this could still happen, especially since we also know that sometimes the problem of inconsistency is an obstacle for clubs in Serie A.
At the moment Napoli should be able to take care of that but this problem is still not predictable.
