Subject   st: interpreting the significance level of spearmans rank correlation

hello, 

I have a question concerning the level of significance of Spearman´s rank correlation test. the calculated rank correlation ("rho") is 0.8804. the star indicates that this 0.8804 is significant at the 5% level (probability of error), right? 
however, the shown "Sig.level" value indicates 0.0000. so, what does this 0.0000 mean exactly? tells it that the probability of error is not only 5% but instead 0%? is this a good result?

thanks in advance!
