Trump says 1000 dumb things a day. Tail latches on the one or two he thinks he can prove are right and pretends it means something.
He's just trolling. He's turned into nothing more than your standard 4chan neckbeard....
If he were interested in the truth, or accuracy he would run a statistical analysis of everything trump has said, and provided a breakdown of how many truly came to pass, vs how many haven't yet (of course, here is where he claims that just because they havent doesn't mean they won't, because he can't help but try to troll). Someone actually interested in the truth would then compare the public statements of other presidents to Trump's accuracy.
But he's not interested in truth or accuracy.
He just wants to jump up and put a mark in the "win" column any time he thinks he can. At this point it's no different than the people who jump up and post every time a random non gun murder happens...
