You ask an awesome question! It depends if you take that 'with a grain of salt' or literally. Literally, it is a lie.... but taken 'with a grain of salt' it simply means that you will get better by practicing, but not perfect. It is like, in American culture alot of people will greet you and say, "how are you doing", but they really don't want to know who you are doing, they are just saying, a friendly, hello most of the time.
