You've show a lot of talent, but maybe not exceptional talent - though it may be too soon to really tell. The different between 1:13 and 1:05 is pretty large. To determine if you get down to 65 you are going to need to determine your speed at shorter distances (as someone else said). You'll need a mile time under 4:20 (or at least 4:25). You'll need a 5k in the mid to low 14's (if not under).
You have two strikes: 1) your age. It takes years to become an elite. You're already 31. Yes, you can run 1:05 at 35 after starting late. Look up Jack Foster, but you'll need exceptional talent. Maybe you have it, but maybe you just have above average talent. 2) you're a little on the large size for a distance runner. At your height you should be around 70kg for longer distances. It's not impossible to get down to 70kg, and you certainly have time to do it slowly. It's also not impossible to run 1:05 at your size, but it's harder.
My advice: start incorporating a little more speed into your weekly sessions. 5-6 100m strides once or twice a week building up until you can go 95% speed (can you get under 15 then it's looking good. Under 13, then it's looking much, much better). Your mileage is good. Don't overdo it. Take breaks twice a year and build back up. When you are close to your peak add some faster stuff 10X400 or 15X200 or 6x1000. Get used to running under 3:00/km. Can you hit 10X200 at 34 or under. 10X400 at 70? 6x1k under or around 3:00. You may not be able to at first, but if you have the talent to run 1:05, then you should be able to manage it (better actually).
Now the question is can you be a Pro?Probably not, but what you should concentrate on is getting as good as you can and let everything else take care of itself.
Oh, and maybe find some running partners who are better than your are.
