I think your chances are as good as anyones. I prepared, trained and had all the gear for my first summit attempt last year. Got sick at Trail Camp and hiked back out.
It was still a great hike. While reaching the summit is, of course, the goal, the hike up is full of scenery many don't get to experience.
Be prepared and go enjoy yourself. If you make it, great. If not, it will still be a great adventure. And, as mentioned by the other poster, the mountain isn't going anywhere.
