We should be careful in saying anything that applies to everything.
But this question is very important because what it means is whether everything in the universe can be explained (solved) in mathematical terms.
If we refer only to the physical universe of matter and energy, then certainly the mathematical description of the world is extremely useful and powerful. We not only get a deeper understanding of the physical world but can also predict many things through the mathematical language.
However, there is a small part of the universe in which we human beings are involved. If we take things that arise in the human mind, like thoughts and emotions, feelings of beauty and ugliness, of qualities of goodness and badness, of values of truth and justice, it is difficult, perhaps impossible, to reduce these to mathematical formulas.
Thus, not every quality can be quantified. If we have two tables, one bigger than another, we can quantify them: measurable length, breadth, height, etc. But we we listen to two pieces of music, and find one to be more enjoyable than another, we can’t quantify their melodies. The quality of musical enjoyment can’t be quantified (solves mathematically).
