 He clearly did go to heaven. He clearly knew that he was on his way to heaven. I'm fighting the good fight, running the race. He talked about that all the time. He had a sense of certitude that he would go to heaven. And this is because of God's promises, because God will not go back on his promise. But St. Paul was clear here that he didn't presume to say, he didn't go that far as to say, I'm definitely going to heaven because he didn't know the future.
