Bro the step one is withdraw that money  I mean like all of it from the casino is 20x of your monthly income then it should work for almost 2 years without work.
After the money lending in your bank account than you should not quit your daily job and I 1000% agree with you to not change your lifestyle and put your money now into a work 20x win off monthly income at least 100-200K right. With that amount of money you can basically invest all in into dividend stock.

I don't know about any dividend stock and bla bla bla. Bro that is simple you can pick an ETF that have ton of dividend stock in it that you don't really need to know behind it. After that you can get money at least per quarter and you can enjoy your life without work
