What are my chances of being kia in the Army?

I know alot of people think this is a dumb question so bother telling me that. Im 18, I graduated 2 months ago and i was planning on joining the army national guard in august. my mos would be 25B- information technology specialist(computer/network guy). i meet all the enlistment requirements and 25b asvab score requirements. people who have been in the army say its a great opportunity but airmen and non militaty ppl say dont go. what are my chances of being killed in that mos
