Can confirm. There are even growing numbers of high-quality games/projects on the platform (I explored it recently), including a fully interactive+realistic nuclear reactor and 1:1 DCS-like Airbus A320 simulator.

I suspect the popularity and ease of distribution/development on the platform makes it very attractive for developers with a dream.

Many of the games that actual kids spend time on are the purest expression of gaming slop (half-broken microtransaction gambling hell with schizophrenic flashing colors). Roblox and Fortnite's Islands system are both guilty of this. The problem is kids don't know any better and don't yet understand the value of money. The obvious response is "parents should handle this" and while I agree, there is no system to let them say "here are Robux/V-Bucks you can spend on quality content (e.g., Fortnite's Battle Pass is very well designed, quality content), but gambling slop is disabled".

Roblox accounts for about 50% of total video game play time, it’s insane how big Roblox is.

But not just Roblox. People are spending their time and money elsewhere too. Polymarket and sports betting for one.

Roblox is indeed eating the world
