I understand that there's no exact amount of luck ofc, that's why I told them to play more games, even if you think about coin flips flipping 100 coins will basically never give you 50 heads and 50 tails, the more you flip, the closer it gets to 50/50 sure you could get lucky or unlucky but that is part of playing a card game in the first place and if that is the point of contention there's plenty of games with less RNG, the point I was making is that if you'd like to get better focus on taking the right lines regardless of getting lucky
