I, too, feel like crash ones make you lose easier but as far as the theoretical side of the game goes, it should be as risky as dice, poker or any other gambling game - totally depending on luck.
I hope that nobody with many years of poker experience reads this, then they would probably give you the boot
The topic "Is Poker Skill or Chance" is quite well researched by now, there are several studies about it, even from renowned universities like the one in Amsterdam:
We found the tipping point: skilled players can expect to do better than their relatively unskilled counterparts at least three quarters of the time after 1,471 hands have been played.
In other words, poker becomes a game of skill after around 1,500 hands. To put this into perspective, most online players are likely to play 1,500 hands in 19 to 25 hours – and less than that if they play multiple tables at the same time.
SourceOf course, luck also plays a factor that should not be underestimated. Everyone of us knows the situation where complete newcomers at the table have really good hands and maybe even win the table. However, this is not permanent, especially when it comes to money.
At tables where money is involved, the factor that, in my opinion, is crucial for a good poker player comes into play very quickly: being able to control yourself and your emotions.
So no, in my opinion, poker is definitely not a game where it's all about luck.
