Meaning of 祝愿 as wishing or congratulating I wrote 哇，祝愿碰运气，能碰上这个组啊. By this I meant I wish I can be lucky and end up in that group. I am worried it will be taken as congratulations on you being lucky ending up in that group (which sounds like "I think you are just lucky with no ability"). 

Does it sound like I mean the latter?
