It depends a lot on what the executable does. I don’t know the hello world size, but anecdotally I remember seeing several go binaries in the single digit megabyte range. I know the code size is somewhat larger than one might expect because go keeps some type info around for reflection whether you use it or not.
The Golang runtime is big enough by itself that it makes a real difference from some WASM applications, and people are using Rust instead purely because of that.
