The big win for Inter Milan doesn't mean they will win the scudetto this season because this the first match of the season there are so many matches to play but the win shows how prepared they are for the new season the motivation from the win will fuel their energy to do more and with the help of their new manager the team should do better than last season or the manager will have the risk of losing his job.
The Scudetto is still a long way off. It would be foolish to predict the Scudetto winner based on the first match of the season, just one match has been played. Here you can certainly share expectations with your favorite team, but a good first game does not mean that you are going to win the Scudetto. Torino are definitely a good team and there is no room to think of them as weak. A big win against such a team will boost the team's morale and show how prepared a team is.
