If you count the remaining matches, it might be true because it is difficult for the team below them to get 4 to 6 points in the remaining two matches so that Roma's chances are much greater. But to ensure this opportunity, Roma must take advantage of the two remaining matches so that they can qualify for the play-offs without having to wait for the results of the teams below them. Roma is indeed not favored this season because of their inconsistent performance and even for the competition in Serie-A Roma has performed very badly with conditions like you said.
Another additional question: does Roma need the Europa League? Why do they need 2-4 extra matches there if they have no chance of winning the title? They have more important tasks in Serie A - they are currently just two points from the relegation zone. There is a potentially easy game against Parma, but then Milan, Lazio, Bologna. If I were them, I would be more worried about that.
It is only fitting that Claudio Ranieri allocates most of his players energy to Serie A, although the Europa League matches cannot be simply ignored. AS Roma might be able to reach the Europa League Round of 16, albeit with great difficulty, but I agree that they should be more concerned about their fate in Serie A. Actualy, the match against Parma, in my opinion, will not be easy to win, especially when facing AC Milan, Lazio, and Bologna, who are currently performing much better. In my view, a major mistake made by AS Roma this season was dismissing De Rossi too early. Overall, AS Roma is experiencing a severe decline, where their chances of reaching the Europa League semifinals like last season seem unlikely to materialize.
