One thing that you need to understand is that, gambling is not what you chase profit all about and believe that you will definitely achieve it. The house edge always win, therefore, how do you expect a gambler to turn 1k into 10k in 12 months. For some, the 1k will end in one week, while some in one month. It's better when gambling, you don't have big hopes but only gamble for fun, and if you get lucky to hit the jackpot, it will be an additional benefit for more fun.
In many other threads, most of what I see is people claiming that they only gamble for fun, they never considered gambling as a place to make money. But this topic shows the opposite, clearly a part of us just want to make money or get rich from gambling, which people always deny.
While this is OP's decision and has nothing to do with us, I agree with you that using gambling to pursue profit is a mistake. Because gambling is not about making money, but about spending money. Given that profit target and time to achieve it, I think it would be more feasible if we consider investing instead of thinking that we can make such a large amount of money from gambling.
After all, people gamble for profit and not for fun as people say and I am not surprised by this .
