Yes, ive played professionally. To be charitable I’ll explain it to you. In poker you play a massive number of hands and if you are good you play a preplanned strategy and sometimes when following that strategy you lose but over the long run, assuming you are playing a winning strategy, you make money.

The luck is seen in the short term fluctuations but over the long run when executing your strategy there is no luck.

This requires proper bankroll management among other things.

Also starting a business is easier than poker, poker is zero sum (more often negative sum due to rake).

Business is positive sum. What this means is people will gladly hand you money if your product generates more value for them than holding that money does. In poker, every single hand is like a fist fight because there is always a loser in every hand.
