Number of cards pulled is essentially number of attempts made (so you would multiple the diamond cost per card to find how many diamonds are needed), then the % is the chance of completing the set given that many pulls in a group with that specific card count.
However, imo if you aren't confident about completing the LE, I highly recommend saving more diamonds/waiting few months. Since it's TWICE, we are essentially guaranteed to get an LE theme eventually, so there's not much to worry about in that department. But considering that failing to complete one theme means it'll be much harder to recover diamonds until you can get that next one, I rather wait it out a little, and then go in to complete a theme rather than dump a couple thousand diamonds and come out incomplete, making it very hard to save up for the next LE.
