I've worked as a developer for online gambling games for 6 years. We never shuffled the deck of cards. Instead, as player requests another card(s), they are generated using hardware RNG and returned to player. Deck only knows which cards are left in it, but their order is undefined until that call to RNG.
You are correct. As the matter of fact, a bunch of games in majority of cases needed only the next card from the deck, that's why in our heads we almost always thought of "not shuffling at all".
How is that better? You just don't want to spend the time to shuffle a deck if only a few cards will be used? Or you are worried someone might cheat by being able to read card order ahead of time?
