I agree, i have to say that Napoli has had a great championship and deserves to remain at the top even if in the last few days it has lost a bit of bite
Inter will have to be careful and win to keep hope alive, and they have to watch what Napoli will do. This final is very exciting
Of course Napoli chances are higher but I have a little doubt not without reason, just look at them they should have won the scudetto last week but what did they do? they threw away the opportunity maybe the same thing will happen to them next week and this is the same as what Inter did. The scudetto fight in my opinion is still 50/50 for both teams. I don't remember the last time the Serie a championship fight was like this, one which certainly makes the race more interesting.Inter will have to be careful and win to keep hope alive, and they have to watch what Napoli will do.

Napoli could have secured the title a long time ago especially because they focus on the league but as you said Napoli often waste opportunities and the last game against Cagliari. Of course, even though Cagliari's position has not changed anything in the standings, they have the motivation to close this season with a win and of course they also don't want to make it easy for Napoli to win the scudetto title which is already in sight.
Likewise with Como, they will not give an easy win to Inter, Como this season has always performed impressively against strong teams, they have a greater motivation to beat big teams. So yes, the chances of both teams for now as you said are still 50/50, a small mistake will bury their dreams of winning the scudetto this season.
