Chi Sao,does it have any purpose in real fighting?

[CredoTe]

Yes, it most certainly has applications. In Okinawan Karate-Do (Japanese styles do this, as well), we have what is called kakie. It trains students in sticky hands / weighted hands similarly to Chi Sao.

Chi Sao teaches transitional changes that are much a vital part of close range techniques. Add that to some wooden dummy training, yes, I'd say it's quite effective providing one devotes some serious training to either.

Can you tell me is a Chi Sao helpful for Karate championship because right now I am looking for a technique which helps me to warm up before the karate match. If some other technique, please specify. Thank you!!!

I believe that it does, and it will help because Chi Sao can, and does, help practitioners learn to embrace close range techniques. Many little things come into play when training Chi Sao, i.e., footwork, transitional shifts, deflections, directings, traps, arrests, checks, penetrations to name just a few.
