Yeah I don't understand why teachers still let kids pick teams. There is ALWAYS a person left last - a 'loser', no winner. You'd think they'd have realised by now that team picking is a cruel and unnecessary thing.

Exclusion from activities is considered bullying/hazing in the rules of pretty much every half decent foundation. Also, if they didn't choose OP for an 'activity' that involves vey sport like rules and movements, they aren't going to choose them for a 'sport.' Overall, the counsellors need to get off their ass and do their job instead of turning a blind eye to bullying, before it escalates. (And this sort of bullying? ALWAYS escalates. Next it will be OP can't find anywhere to sit for lunch or people taking their stuff. I've seen it happen a lot.)

So because OP got excluded one(1) time, you are guaranteeing that he will be excluded for any and every activity while he is at camp and the bullying "will" escalate because you've seen it a lot of times? Instead of assuring OP that things will get worse at camp you should try to be positive and give him some advice on how to deal with the situation and hope that he doesn't get hazed or bullied.

Ah, frank, at it again with the 'oh maybe things aren't that bad' perspective. Look, I'll argue for the sake of arguing more than anyone, but this is a clear case of exclusion and while it doesn't technically count as bullying if it only has happened once(1), it's still nasty and hurtful and yes - if there are no consequences for the other kids' behaviour it may very well happen again. This isn't like some lottery ticket where it's like 'aww, better luck next time', these are kids deliberately excluding one kid and heck while they may have their reasons (maybe OP's an asshole? <-- that's a route the devil's advocate could have taken), things aren't just going to 'get better' if you 'think positive'. Someone (a camp counsellor??) needs to explain to those kids that what they did was hurtful and if there is some animosity and/or justification for the exclusion, sort it out productively.

Yeah. I hope this incident doesn't get worse or escalate to bullying. And I hope that OP isn't an asshole. But from my experience growing up, the kids who are assholes don't get left out, usually they're the ones picking on kids and giving almost everyone a hard time. The positive perspective is just wishful thinking towards OP and anyone who feels hurt or not wanted. I hope things only get better for OP while at camp and that no kid gets left out or bullied. But that's like wishing for world peace.
