If you'd like to make money you need to code more complicated things like
a betting martingale bot.
I think he is not making money here because the title is FREE. Even if he can code a betting bot, he will need to code a betting bot that is better than seuntjie's bot and it is hard to sell it as well because seuntjie's bot is very famous around here
as I remember first he wanted to sell it , but because there are many free calculators he changed his mind
