I think more often than not the all-in bets make you lose your bankroll rather than save it, but there have surely been times especially in poker for me that I kept going all in even when I had practically nothing to lose and I came back and made a killing! My favorite game to do this one tho would definitely have to be roulette.
wouldn't it be very risky to lose it all when you decide to go All-in.
In one good moment, of course, it will give many benefits, but the risk will also be greater.
I didn't even have enough courage to do All this, even though it looked like a victory.
Doing management and leaving some money would be better as a backup.
Victory will not always come, there will be defeat that will also come to anyone.
There is a risk of losing everything when you go all-in, but if this is poker, then it seems to me that the math is different: if you have an over hand, then without going all-in at the right moment you will not get the maximum that the over hand gives you (option when your opponent will fold his cards in response to your all-in, we will not consider). If you are bluffing, everything is also clear: all-in is the best bluff and if you don’t do it, then your opponent can answer 5bet with a greater probability.
