Gambling bots usually have neutral profitability.
They execute orders or strategies set by users. Not more not less. There is any magic behind
As example, I have used Geek toys for sports betting in the past.
With the right strategies, thanks to its speed of execution of multiple simultaneous plays, the results were literally devastating and impossible to achieve with a manual play. (likewise in horse racing with multi bets to be placed live in the right time, or using the function "all green" etc....)
But to win with a bot you need the right strategy or the correct setting.
Without these two things it is unthinkable that they produce results, indeed, they can only make a bettor lose much sooner
Other types of bots (for example those in the dice) can make you win, but you must ALWAYS keep in mind that there is a HOUSE EDGE so the dealer always has a basic advantage and it is really difficult to overcome this situation... for sure they can help to save portfolio and avoid useless bets. Otherwise it's just a risk and there is any real advantage for the player
