The only place an "all-in" is acceptable is only on a poker table.
I think he mean about all in if you deposit and then you bet all of you outstanding balance its called all in.. yeah we know that about poker there's a option in poker that you can all in depends in your cards. But its risky to do if you really don't know how to play poker..
If you don't know how to play poker then you should stay away on that kind of game, otherwise you are just wasting your precious money. As a gambler we need to select our games where we can have a good advantage to win in the long run.
