springというプロセスが動いているとconsoleが起動しないことがある、とのことで bundle exec spring stopでkillしてみたが、Could not locate Gemfile or .bundle/ directoryという結果。

rails console は rails のアプリを作ってその RAILS_ROOT に cdして初めて使えます。
表示されるusageに rails new APP_PATH [options] とあるのは rails console の console が 素の rails のサブコマンドに無いから、素 のrails の使い方が表示された、ということです。
rails new でできたアプリのdirectoryにcdすると そこに bin directoryができそこに rails というコマンドができています。rails console はそのrailsのサブコマンドです。
おまじないをしないと bundle exec rails console としないと起動しないかも。
