Casual is a nebulous term, but perhaps "widely accessible" is easier to evaluate. We can measure accessibility by games sold.
By sales, the highest-selling games are [1] Minecraft (now AAA), Grand Theft Auto V (AAA), EA Tetris, PUBG (before becoming freemium), Mario games, Pokémon, Terraria, and Red Dead Redemption 2.
So by sales, the vast majority of top-selling games are AAA. For what it's worth, I think similarly to you about preferring indie games to AAA games due to lack of time. But for most gamers and people in general, I don't think people even calculate the 40-60 hours per week. Most players probably just spend a lot of free time and weekend days gaming, and then the hours add up.
You do have a point that a large number of players play free-to-play games (e.g. League of Legends and many phone games), but there's a fair argument that AAA games are also targeted at "casual players," by evidence of their wide popularity in terms of massive sales numbers.
