You asked a great question. One of the most interesting characteristics of our Universe is that it is build up from very simple elementary components from a set of very complicated rules. The rules never change, but as the simple objects come together and form larger and more complicated objects, new "emergent" behavior appears that you would not have anticipated from simply looking at the basic constituents of the larger object.
The key word here is "emergent", meaning new characteristics appear at ever increasing levels of complexity. An example of this is "intelligence". At the cellular level, neurons are just passing electrochemical signals back and forth. But when there are billions of neurons interconnected by trillions of neural fibers, we get an entirely different thing.
So even though quantum physics don't apply in our everyday experience, it is NO less sensible or valid.

the effects and phenomena that quantum physics describes, becomes less apparent at the macroscopic level, such as the world we live in, and even further to the solar system etc...
classical physics describes our world quite well within limits.
At the smaller scales, quantum effects become more noticeable, for example, the 5th state of matter, bose einstein condensates, are a state of matter that is held at such a low temperature (close to absolute zero), so that it contains very little energy.
Hence friction forces do not lower its energy, and it exhibits very strange quantum behaviour, such as intefering with itself, just like quanta of light, electrons/an electron through a double slit.
It is only because we are so large, that we find the very small so difficult to comprehend.

It doesn't have to make sense: it just has to describe how the world behaves, which it does supremely well.

Keep on studying and then ask again.
