Core 2000 and Kaishi 1.5K

Stupid question but what's the difference between Vocabulary and Kanji? My grasp of understanding on this is that Vocabs are like the Kanjis with Hiragana, which makes the complete word (Ex: 好き), while Kanji is just the standalone character (Ex: 好).

Another question is that I am trying to have two separate Anki decks for Kanji and Vocab. Is the Core 2000 the Kanji deck and Kaishi 1.5K is the Vocabulary deck?
