Do they conceptualize this way?

As in any language, native speakers absorb words as they mature from infancy to adulthood. They learn from example and instruction the context or syntax of words. You only have to watch a mother and a small child to see how the child is learning from the mother, and how the mother will correct the child. 

However, apart from the basics of the language, they will also need dictionaries when they encounter words they cannot identify or interpret. Choosing one dictionary against another seems almost impossible, and it does often look as if they are using different concepts. It is the problem of trying to make complex concepts simple. Sometimes the definitions themselves seem over-complex, or the way they are presented is confusing.

Which dictionaries do you use?

Thank you, Feeb11 and Nona.

I think I have asked a similar question and Nona made a good comment. My question this time is for words like 'experience', for which one of the dictionaries I have, which is the Collins Cobuild Advanced Learner's  English Dictionary,  seems to list about three noun definitional entries, aside from one entry that said it a noun used in a N of N format, and they are roughly as this:

N-UNCOUNT  Experience is knowledge or skill in a particular job or activity, which you have gained because you have done that job or activity for a long time.

U-UNCOUNT  Experience is ued to refer to the past events, knowledge, and feelings that make up someone's life or character.

N-COUNT An experience is something that you do or that happen to you, especially something important that affects you. 

I think I have asked a question about the word 'experience' in a secton of these forums and the responses I got seemed to have converged to the fact that I shouldn't rely on those definitions so much but should think of it as a matter of general vs. specific differentiation.

One other dictionary I have is a paper back version of The Merriam-Webster Dictionary and the entries there do not have notations for countable, uncountable, or variable categorization.

My guess is a native speaker is more likely to use The Merriam-Webster Dictionary, rather than the first dictionary I mentioned, and that gave arise to the next question of "Is it possible that English learners need a multi-entry dictionary to sort out the category dilemma but native speakers do not need to look at the kind of the first dictionary I mentioned to sort out the category dilemma; and the dictionary of the first kind has many entries for the word 'experience' in order to custom-serve the English learners in  non-English speaking countries.
