If I were in desperate need for bitcoins I will gamble everything that I have in dice games. It is a very risky move but at that moment luck was my side and I won 0.1 in one go in 5 minutes of crazy bets started with low capital of 1 million satoshi which is all i have at that moment. It helped me a lot but today when i tried to do it again luck was no longer on my side and I lost everytime but at least I have a stable source of bitcoin right now so theres no need to worry.
With gambling you may win once or twice but you cannot expect the same in long run and you cannot depend only on gambling in case of any emergency as there is no guarantee of winning everytime.
