Game bots and social media bots are entirely different beasts.
If you want to create a game bot for a MMORPG its a massive process and you basically have to reverse engineer the game in order to find the hooks and what not.
I know some of the runescape bot creators (not the script writers for these bots) we making over a million usd a year from them.
If you can find a game bot program already made you can ethier buy public scripts (which usally arent the best) or get a custom script coded.
The botting community keeps it self to itself because the risk of being inflitrated by do gooders and the game creators employees is high. You will hear a lot of the time that people moan that bots dont work anymore and Jagex have got too goood at detecting bots (I can only speak for Runescape). This is bullshit the bar to entry has been lifted considerably but I have seen for myself raids 2 bots which are making over $600 per server per day.
Social media and web bots are a different beast a lot easier to create though the difference between 'It'll do' and 'maxed effiency' is enormous.
You can write bots that will work well enough in puppeteer and nodeJS.
In order to get maxed effiency on a server though you'd want to strip down chromium to the bare neccesitys and work on your own system of PVA's (a sim bank and searching on ebay for bulk sim cards will get you started).
Really though if you can code and you have a subversive personality and are paranoid as fuck you will do very well in the botting scene
