The distinction between studying Latin and learning Latin is highlighted in this article by Mark J. Clark, of Christendom College. My own kids have studied Latin, but not learned it. I'd say even my son that is majoring in Classics does not practice much "living" Latin in the way that Dr. Clark means it. He can correct me in the comm box if I am wrong. I'm very much in agreement with Clark about the necessity of learning Latin as the key to our Catholic heritage and as an exercise in a significantly different way of thinking.
