Answer 2

Steam gift cards are generic gift cards which can be used for many games on steam, including team fortress 2.

Some steam gift cards have featured artwork for team fortress 2, but any steam gift card will work regardless of which game is pictured.

Steam gift cards give you a 'wallet code', steam wallet funds are than what you use to make purchases in TF2.

There are also 'Holiday Gift Cards Collections' from the valve store which feature team fortress 2 artwork; but these are actual note cards which you would use for birthdays, Christmas, etc and not cards with money/credits for the game.
