How do you not lose money when raising most of the time preflop?

Of course, you may bluff or be bluffed, but as a beginner, that's a complication that we can talk about later.

In poker, winning is the same as not losing. At the end of the day, whether you won $100 more dollars or lost $100 fewer dollars, the result to your bankroll is the same (it would have $100 more dollars than it does).

You may not understand the 80% either.

It's not recommended that you play 80% of hands that are dealt to you. It's recommending that when you DO play a hand, that you play it aggressively.

Let's say your range for UTG is { 99+, AQ+ }. That's only about 5% of all possible starting hands. When you get dealt one of these hands UTG, then you should probably raise with it. Even if you raise 100% of the time with that range, you're really only raising 5% of all hands.

Just because you do not have a pair on the flop does not mean you have the worst hand. You are only going to make a pair 1/3 of the time, but so is your opponent. That 1/3 is evenly broken up into when you do and don't have a pair, so it's the same in either case.

This means that whether or not you have a pair on the flop, the chance of your opponent having a pair is ~1/3.

Thanks for your insight, the BIB however I think you misunderstood. I know not to play 80% of my hands, that would be ludicrous, but meant raising 80% of the times you want to play a hand.
