No this is not true and it's actually a common misconception. It is not true that doing something for a long time makes you better at it or more knowledgeable about it. There is an excellent meta-analysis [1] that looks at domains such as music, games (such as chess), sports and other domains that shows that people must put in deliberate practice and make an explicit effort to improve, otherwise they simply stagnate and get into a bit of a comfort zone with little to no improvement. When it comes to programming I often say that there is a difference between someone who has ten years of actual programming experience, and someone who has two years of experience that they just repeated five times. I can state from experience that there are plenty of C++ developers who have been using it for decades who don't know basic things about it, and use it like it was still 1995.
