Yes, automating the gambling process is the main goal of using bots but I'm not sure if using bots is to avoid mistakes because if we don't control the bots that are running, it can cost us a lot. But I don't know, I have no idea how to use the bot for gamblers. It will reduce the fun of playing gambling and maybe the tension will also not be as big if we play gambling manually. Everyone will have reasons for using bots or prefer to play gambling manually.
Gambler can get some advantages from using bots as well as disadvantages. To get a good bot or software he must spend money. On the other hand the bot should be set properly. But here you are not guaranteed to earn money. Moreover, you will be deprived of the pleasure of manual betting in gambling. I don't use gambling bots and do not intend to do it.
