Like you can't just put 100 dollars into any casino and hope that you could turn it into 1000 dollars every week and make that a job, maybe you will get lucky and win big, but that would be few and far between, with a lot of loss in the middle. So, being part of the casino itself is a bigger possibility to make a profit compared to being against the house and gambling against it. House edge is literally there to stop people from bankrupting the casinos after all.
Whatever it is in gambling it is difficult to guess whether their gambling games will succeed with profits or not, because if we have capital of $100 for example it wants to be 10x in gambling then it's not possible unless luck siding with you in gambling games is difficult to win even often losing in the middle of the road with the emotions we face is therefore consistent with gambling I think is useless.
