Nah, video games are and will always be at their best when a small team is bringing a new and unique, or a fresh and refined, perspective on something.
Rimworld, Kenshi, Stardew Valley, Grim Dawn, Project Zomboid, Palworld… none of those needed big budgets and large parent companies. My Steam wishlist has over 100 games on it currently, and maybe 5 of those are AAA titles. There’s plenty of great stuff still coming.
