Nikon Coolpix L820, is it a professional camera?

I own a Nikon Coolpix L820, and I'm going to a concert early next year and plan on taking it, I don't have another camera and my phone, lets not go there, it's horrible. And no, I don't have the money for another camera because I'm paying to go to another state so, airfares, accommodation, meals, transport, holiday stuff, Christmas would have not long been and gone and I will also have car payments too so yeah, I'm rambling now.
Anywho, the stadium says no professional cameras, so I've tried to find out if it is or isn't professional but no luck.
If someone could give me an answer and/or tell me how it is or isn't professional, that would be fantastic! Because I was told it wasn't professional when I bought it and then I was told it is classed as professional by a venue I went to last year, just because it wasn't a smartphone or small pocket camera. All help and thoughts would be fantastic! :)
