Not to defend the TIOBE index (claims to be a measure of popularity of programming languages) but if you go by the dictionary definition of popularity ("the state of being liked, enjoyed, accepted, or done by a large number of people") I don't doubt that Scratch is more popular than Lua, Scala, Kotlin or Rust. If I think about my friends and acquaintances, most of them certainly have never heard of any of those languages, but I'm sure almost all of their kids were exposed to Scratch at some point.
