That's because you're using a text-mode console, as opposed to running
Emacs under X, or Microsoft Windows, or OS X.

In text-mode consoles, the keyboard is capable of delivering only
ASCII characters (or sequences of them) when you press a key, and in
ASCII, control-[ and ESC _are the same character_.  They're
indistinguishable.

(They even do the same thing in my Windows Emacs, although there, I
suspect it might be possible to distinguish them, with some wizardry.)

Yup.  Same deal.

Other than "use a window system" (which as you can see isn't even
sufficient), I can't think of one.
