Agreed. If $500 is your target, you have a chance of hitting that target of 42%. That is a much better chance than flat-betting thousands of $1 hands on a negative EV game (like blackjack or any other game).
The only consequence of that is: Stop playing the game the way you are playing, right now. $500 is lost - it is not going to come back. Stop chasing your losses, it will only make matters worse.
If you want to learn how to beat this game, you already found the right place to learn. But then you have to listen carefully, ask the right questions, and most importantly do your homework. First lesson is gameplay, second lesson is basic strategy. Next lessons are counting systems - first in theory, then in practise. Then still in practise, and only then in casino.
That's what it takes, along with an open mind, and much more discipline than you showed until now. You might get your $500 back, but you have to work for it.
