When we do talk about probabilities then these card games do really have it and comparing it to other games like luck-based ones isnt really right at all.
Experience and skills is needed with this kind of game but overall these factors wont work out if luck wont be on your side.Therefore, all these 3 things will needed along the way.
Thats why Poker is similar to trading. You never know when big player will come and push price untechnical or when bad/good news will appear. You may have bad luck 9 times out of 10 and still earn if you know how to do money mangement well. Same with poker. You can have bad cards 9 out of 10 times and pass lossing small portion of money and then with one good set put yourself into profit.
Poker need experience, skill, big balls and on the fourth position luck.
