In La Liga it really already seems that there is no chance, despite the fact that there are still a sufficient number of matches, but if we assume that Barcelona should lose these matches (albeit not all), which is impossible in principle. On the other hand Real Madrid still have a chance to take the Champions League trophy, and the chance is great enough
The distance between first position and second position is indeed very far and impossible to catch easily. Therefore, the La Liga match may end quickly because it is already known who will be the winner, but this match will still be interesting when used to do gambling and make money from the results of bets in each match.
