Except it's not a good argument - if you believe knowledge is equivalent to experience. In order to understand what ammonia smells like I need to understand how the mind as a whole interprets the presence of ammonia. Once you have understood how the mind interacts with ammonia then you know what it is like to experience the smell of ammonia. You might say well, I can imagine how it must feel to understand how the mind works and my internal model of how it must be to understand how the mind works indicates to me that this would not allow me to experience the smell of ammonia. But you would be wrong. Just as the machine in the Chinese room argument understands Chinese and understands that part of the world described within Chinese.
