well if she did lose I'm not gonna say "HAHAHAH YOU FUCKING LOST GET GOOD KID!!" no im gonna say better luck next time, you never bring someone down because they are not perfect. you have to push them to perfect the sport.
+YourNameHere I think the reason they were saying it's rude, is because you could have asked 'Did you win?' Which would have been a more positive question, as it sounds like you were expecting her to loose x
