Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

There is a difference.

Say you buy a used PC or android stick and want to use it for piracy, ok, doable, but you'll be doing most of the work. Kodi builds can get you there easily.

but compared to firesticks?

Firesticks have a piracy singularity going on. The entire secondary phase of cracking the OS and installing is intended for piracy. It's an open and shut, easy, one-two punch to get into the ecosystem. All of the hardware is easy to track and maintain. My cousin has a hacked firestick and he can't even open Microsoft Word. You can buy them pre-hacked with no real input or work needed on your part.
