If bots were good for gamblers casinos wouldn't provide it or let us use this kind of system to make automated bets. If they let us use bots it's because they know we can't win in long run.
With or without bot it is the same, you will lose in long run, as i said before bots are just making things easier, nothing else.
However, it can be useful for some things like help us to increase our stats automatically.
True, if there is some sort of wagering contest or you just want to increase faucet bot can be helpful.
