It is close spot. I would tend to call here for several reasons:
1. Maybe this is not top of your range, but still this is tptk, so if you are folding this here, than it means that you call only with
hands like any nine, 22, 33 (TT you would probably raise preflop). I think on such board you will be exploited.
2. You didn't write on what number of hands the stats are calculated, which is quite important here. While Af is very low here, this is also draw heavy board. Villain could be aggressive with many hands here, like 78s, JQs, JKs, JQo etc.
3. If you called the turn, you should called the river. The only hands that really improved here is any nine, draws have bricked. If somebody is barrelling, you have to assume that he will barrel on the river as well either for value or
bluff. So you cannot call the turn and then fold the river when all draws that made sense to bluff bricked.
I wrote that this is close and here are the reasons that imo make this call a bit tough. You have Ad, which actually you really want him to have. With his stats it makes a lot of sense for the villain to continue with any suited ace here. Because he can have any Axd in his UTG open range or at least A2-A5 and AT-AK. Also his AF is low, but then I am not sure what was the number of hands on the HUD. But then you should probably fold on the turn if you think he want be aggressive with draw only.
Bottom line - when calling the turn here you should have already clear decision to call on pretty much any card that is not diamond and maybe K or 6 as those cards are most likely to complete his draws.
