If the output is as above, then congratulations, mactex has been installed successfully. You can proceed to next step.
Otherwise, please continue. We need to fix this. I’m not sure why, but sometimes, after brew install mactex finishes, it just downloads a package to your disk. You still need to install it manually.
brew info mactex
