There are ways to keep the odds high for the house now, they can do multiple decks together and shuffle mid-way, so you cannot just count cards like before. If it works there would have been professionals who live off black jacks, and currently people are better off working min wage jobs in the long run than playing black jacks all day.If you're going to be gambling, at least do it on something where you have some control and where some skill plays into the game, like Black Jack. If you have a good memory for remembering the cards, you can improve the odds enough to make consistent money. Scratchers are pure luck, which is just an imaginary concept.
