In the end every hand is for itself, or every throw, or every spin, depending on the game you play! And for each bet on anything you choose your odds! You can't separate winning from losing in gambling, both plays important role, watching for long streaks of winning or loosing is important, you need to adjust your bets after long streaks! If you wish to be profitable in the end of the day you need to catch the right moment for aggressive play, when you rise your bets and odds, and win can bring you back what you lost and add some cherry on the top.
In long run casino wins, we can't compete with their bankroll, so once in a while take a break, change a game or casino.
Unfortunately, the chances of beating casinos are near zero, even if you are the luckiest person in the casino, hitting a 1000x bankroll win chance is not possible. Einstein has explained it well: "The only way to beat roulette is to steal money when the croupier isn't looking". Aggressive, progressive, conservative money management rules are forms of controlling your bankroll, it has no effect over winning/losing odds.
I can see you are not a gambler, aggressive or conservative has effect over your win/losing odds, simply it's basic in gambling, if you bet 1 at odd 2 you will win 1, if you play aggressive and you make higher bet on higher odds you will win more, or lose more. As I said, catching the right moment is essential, and who gambles catch that moment from time to time and make money! If you play conservative with low odds you can win a lot of money, but you can't lose a lot either. Bottom line is what you do and how you do it will have effects on your bankroll, and winning/losing odds.
I said the same, chances of beating casino are low, but from time to time if you are lucky and you catch your moment with your gambling style you will win some nice amount that will cover everything you lost, and maybe put you in some profit. Happened to me to win over 1 btc with 0.05 (more or less starting bankroll).
