Systematically, Real Madrid still has the opportunity to catch up to the 12-point difference that is now in the standings. But Barcelona will not be so stupid as to let Real Madrid catch them easily. They have performed very well this season and can even be said to be better than Real Madrid, this can be seen from their several meetings which ended in Barcelona's victory. Now that they are close to the title, they will not miss this opportunity.
As Xavi said, 12 points ahead of rivals Madrid. doesn't make them satisfied, approaching the end of the season Xavi and his team must be more consistent to stay on the winning path. after all, La Liga still leaves 12 matches until this season ends. meaning, Xavi must maintain the consistency of his team in more crucial phases. at least, if Barcelona confirms the title, they have to win 9 of the remaining 12 matches. not an easy journey, because all the other teams will also focus more on increasing their rankings.
Meanwhile, it doesn't mean that Madrid doesn't have the opportunity to reduce the point difference from Barcelona. Don Carlo could have focused his team, to focus on winning the remaining matches. plus, hope that Barcelona will slip 4 or 5 in the next match. With that, Madrid has the opportunity to overtake Barcelona. However, this is just my scenario and doesn't mean anything. well, let's just enjoy it when these two teams play game after game until the end of the season.
