You've just admitted that the way you use "learn" is different. It's you who is using it differently from the commonly agreed upon way. (3) is arbitrary, ideally you would want to remember the words for your entire lifetime. A lot of people don't care about (2), you'd only care if you want to live in the country and are presented with a lot of paperwork.

You learn the words for a day (you're able to match the sounds and meaning to it). You will forget a lot of them tomorrow, so now you have to re-learn them. This is just how Anki works. You keep learning and re-learning until they stick for a prolonged period of time. It's common for Japanese learners to add between 20 or 30 words to their learning queue.

If you understand how Anki works, you will also understand how the word learning is used in relation to its flashcard mechanism.
