Christopher Strachey wrote a version of draughts/checkers for the Manchester Mark 1 that was fully functional in 1952. This is IMO the first video game. Earlier candidates use single-purpose display hardware, which disqualifies them from being "video".
Computers games can have no video at all why the 'display' it's being sent over a serial output to either a display or a printed paper.
Nethack/Slashem, text adventures, Sokoban, Trek... can be printed one sheet at a time and be totally playable. With Slashem it might be a big waste of paper, but with text adventures you can just reuse the output (obviously) and reduce tons of further typing because you already have the whole scrollback printed back in your hands.
If the wikipedia image is accurate, its technically not "displaying" the board, its just in ram. The RAM just happens to be visible. But you get into a lot of technicalities when talking about the "first video game", so its up to interpretation. There was the "Cathode-ray tube amusement device" in 1947 that, by some interpretations could also be the "first video game" https://en.wikipedia.org/wiki/Cathode-ray_tube_amusement_dev...
I think it is at least safe to say that PONG isn't the first
