Speaking about future and investments, I don’t think of gambling as an investment because even if it can be based on statistics, it mostly has to do with randomness.
Gambling isn't an investment but if you take part with those bankrolls investment, you are investing on the casino and you're with them.
But if you gamble alone, you're the customer and gambler where they are earning.
Why not invest into a business or a skill, or something that can bring you money over time instead of planning to gamble with all you have. The top gamblers actually have real jobs, even if it is providing PAID expert predictions like in this thread.
Although this takes time but this is more of an assured way for you to be an expert.
