There's reading people, doing math on what cards are left and what to exchange, and knowing how much to bet based on the betting habits of other players. A few other minor psychology and math tricks.
Then there's the entire rest of the fucking game which is you get a random card from a deck. Are you seriously disputing this?
(I know this is seriously off topic, if needed you can move it to the hobbies thread or something Ozz)
You shouldn't talk about things you don't understand with such arrogance. You have a very basic understanding of the game, and are technically correct about a few things, but there are so many more layers of knowledge that you haven't learned yet. You also don't exchange cards in anything except some stud variants or pineapple.
Examples of things you need to master to be even close to profitable: using table position, bet sizing, continuation betting, bluffing / psuedo bluffing, blocker bets, post flop strategy, preflop strategy, stack size strategy, 3 betting, pot control, pot odds calculation, reading ability, aggression vs tight play, cash game vs tournament strategy, table image, deception, etc. Also, good players have defined overall strategies they use, such as TAG (tight aggressive), small ball, LAG (loose aggressive) and many others. And finally, the emotional and mental part of poker is huge. A lot of people play solidly until they get unlucky, and then they start playing badly. I struggle with that myself and it takes considerable effort and research to improve it.
Note that all of these things have nothing to do with the hand you are dealt. Just 'knowing when to fold' is lol worthy and I'd love to play with you at any stakes anytime. Most people sit down at the table without knowing any of these things, and you can get lucky occasionally but overall they lose 8/10 times.
