Grad School ~ Submitted Personal Statement Instead of Statement of Purpose
No one can really judge how others will look at your application, but there are a number of people here who are currently involved in doctoral admissions who say they ignore (or merely scan) the SoP. You missed an opportunity to detail your future plans and a specification of field, unless you stated that elsewhere. 

But, I doubt that it is disqualifying. If your admissions materials paint a solid picture of your accomplishments and your letters of recommendation stress your likelihood of success you should be fine. 

But if you have a chance to amend your application, you might want to do that. And fix it for future applications you might make. 

This might be more of an issue outside the US-Canada region, I think, but probably not a huge deal here.
