I think his point is that the players aren’t putting in the work. League position isn’t a direct reflection of whether you are performing to your capabilities.
Conte is a serial winner and when he could be doing better and feels his players aren’t putting in the work he is rightly ****** off.
As he alluded to, they are happy in their mediocrity. Comfortable there. Arsenal are flying high this season. No one saw that coming and everyone would be praising them if they were merely fighting for too 4. But instead they are fighting for the league.
