but when I started playing Dice, I study the pattern and it was working for me and I could double my capital within 30 minutes.?
You studied a pattern in a completely random generated game?
This is interesting, I'm quite curious where you played on what casino and what type of pattern did you manage to find out that would double your money in half an hour constantly. By these results, you could become a trillionaire in a few days 
Anyhow, pretty obviously it was sheer luck, not you guessing rolls from past events.
People look for a pattern where there is none - that's why it's called games of chance - but the best way to convince someone that there is no pattern is to they start losing money, which of course happens to everyone. Even if there was a pattern, does anyone think any casino would let them win indefinitely?
Exactly, I like your opinion my friend, it makes sense to say that there is actually no pattern, strategy or any way that can lead you to a greater number of wins/often. I think it makes sense to say that if it is associated with a fact that in the end the number of losses is always much greater than the wins, and besides as you said that if there was a pattern or strategy that could be used as a guarantee of victory or even to increase the chances of winning (except for sports betting) then surely the casino would not let that happen, and also surely there have been quite a lot of casinos that have gone bankrupt because of the big wins that have been obtained by many gamblers. On the other hand, one thing that I hope is that the more dominant losses can really make gamblers aware that there is no pattern, strategy or any way that can guarantee victory, especially in casino games.
