Let's start with the Nine of Swords reversed. This card suggests that, as far as Luke's ideal is concerned, there is no clear goal in mind. It is a time of confusion and uncertainty. It may be difficult for him to achieve a goal if he doesn't have a clear plan.
The Four of Swords advises, however, to be satisfied. This card indicates that one should adopt a sensible and practical attitude in seeking what is possible to achieve right now. In other words, Luca should learn to accept reality, not waste time dreaming of the life he can't have and focus on how to do better with what he has available.
Adding all this up, it seems that the most probable answer to the question "What do you foresee for the future of my nephew Luca in terms of studies or training?" and "Luca will study". Even if he doesn't have a clear goal in mind right now, the cards advise being realistic and focusing on what he can do now. This suggests that Luke may end up embarking on a program of study or training because he is more likely to commit to something that drives him forward than to stand still.
