The game list from that PlayStation magazine is neither exhaustive nor exclusive. It contains no first-party titles at all, but includes titles like TES6, which the studio has already confirmed won't be with us for a very, very long time after Starfield which is already two years away itself (and also on the list).
You will not see all 38 games on that list, and no others, at the PS games reveal event. It's just a list of games they think will be on PS5. at some point in its life (colour-coded so green is launch, yellow is post-launch, red is a way off).
