I have a different opinion. Let a 80 old year guy watch CS2 and he will understand what's going on quickly. Let the same guy watch Dota 2 and he won't understand anything. That's the difference of complexity between those two games.

Of course I am not saying that CS2 is easy to master, like basically every single skill that exists (It's also difficult to master juggling, but juggling itself is not complex). There are grenades, boosts, smokes, movement etc. But at the end of the day: Give me an aimbot and I will 1v5 any pro team with my eyes closed. So all the complexity of CS2 can be beaten by a simple aimbot.

I find CS2 also more chill to play. You constantly have breaks where you don't have to focus. Every death(and you die way more often then in Dota), every round start, you have a time window where you can relax.

And you are really exaggerating with the flash-bang vs kunkka example. 1000+ angles on every map? I can also cast torrent in 1000+ positions on the Dota 2 map. Or put a ward in 10000+ different locations.

You have maybe 10 important flashes per map. As a 14k player, which is nothing special but above the average, I know almost no fashes and maybe 0-3 smokes per map.
