That's the wonder of playing skill games.
Even with a bad set, you can turn the table, for example with the card-game you mentioned and for other card games as well.
Luck won't just come to us if we don't have skills. And even with a good set, without skills, winnings are not always 100%. But for the part that I will use my skills to rely on gambling to make living, that's a no for me.
It called skilled-games because it definitely requires skills to play. Yeah, if you have the skill you can make a change of the game. That is why if you could look into a game between a newbie and a 10-year-old gambler, you can see the difference in how they play. Because the more you've got in gambling especially in this field, the more you have gained knowledge and improve your skills.
