1099 misc box 3

I'm pretty sure I know the answer to my question but I want to confirm it here. 

 I am a disabled veteran. My only income is my veterans disability payments which I have already confirmed from several sources is not taxable. I am not required to file a tax return . 

 I just recently won a 600 dollar prize which I will receive a 1099 misc with the amount in box 3.  I'm pretty sure box 3 amounts are not subject to self employment tax. 

 I believe that since my only income is veterans disability and the 600 dollar prize is less than the standard deduction and shouldn't be subject to self employment tax, that I do not need to file taxes next year. Am I correct?
