They're everyday accessories for players of card games. A deck box is a small case that holds and protects your sleeved deck, keeping cards organized and safe in transit. A playmat is a soft, roll-up mat you play on — it gives sleeves a clean, smooth surface (reducing wear), provides grip, and often shows off artwork you like. Neither is required to play, but both protect your cards and make games more comfortable, and many collectors enjoy them for the art. They come in every price range. If you're getting into playing a game, they're worthwhile early purchases. You'll find deck boxes, playmats, and sleeves at most card shops.
