no matter how great your strategy in gambling, you will never win.
That is correct because gambling is not made to make money but is meant for having a fun. If you use it to earn money from it then at the end you may lose lot of money and don't even enjoy the games. Hence don't use gambling for earning money.
So you think if you gamble for having fun will not make you losing anything in the end?
No it was big mistake you have a mindset like that.
Gambling is of course about when people realize one day they will get lost and full of regret , any strategy wont help with this fact.
