Though this is a common interpretation for the card, it doesn't really mean that, per se. The 9/Cups really is a card about satisfaction. Particularly personal and emotional satisfaction (this is why some view the man on it as looking "smug"—satisfied).
People tend to read this card as if it's a magic lantern and whatever you're wishing for, you'll get. But that's not really it. First, the card isn't about "things." It's a Cups card. That's emotions. So if you're wishing for certain emotional connections or responses, then the card may give you your wish. But if you're wishing for things, then it's not likely to give you exactly what you're after (Pentacles is the suit of things).
So if you're wishing for a new car, and you get the 9/Cups, it's not likely that you'll get a new car (a thing). The 9/Cups indicates that what will come to you, be it a loaner car or used car or a bus pass, will give you satisfaction; this will replace the dissatisfaction you're feeling now.
