Real Madrid have reached their 14th championship in fact and it is a really huge achievement for them without a doubt. Their nearest competitor in the record winner table is Milan with 7 titles. Because of this situation, there isn't going to be any team to compete with Real Madrid about the number of championships for very long years. This must be very satisfying for them of course. As long as Real Madrid keep this level in the worst case, there is really no way some other team are catching up with them and leaving them behind about this.
It is really silly to think that they have 14, and the next one has 7 which is Milan. So basically, Real Madrid won it twice as many as the next closest team and that is a huge huge huge accomplishment. Nobody has been this good recently neither, look at the last 10 years, they have like nearly half of that if I am not wrong.
I believe that the three peat they had was a marvelous achievement that was shocking to the whole world, but even after they parted ways with most of the players from that team and got new ones, they still managed to win it again. They are just surreal, and when it is UCL, there is no saying in what they will be able to do.
