I'd like to point out, within the experience category, that you won't know what it means until you have it (experience, that is), so saying it doesn't matter is really saying "I have little of it". In fact, you may not really understand that comment until you are wise enough to do so. That's my opinion on it, anyway.
In spite of that, not everyone learns and grows from experience, so to simply say you have it doesn't mean you have matured.
