The stats are from ESPN:

I'm depressed enough to calculate the percentages:
- XP: 0.970
- 0-19: 0.833
- 20-29: 0.907
- 30-39: 0.759
- 40-49: 0.602
- 50+: 0.482
Thank you very much for your service in looking at and calculating this.
My guess is that given that a 38 yard kick is closer to the bottom end of the 30-39 range and on the high end of the 40-49 range the typical make % for a 38 yard field goal without looking at more detail at somewhere in the 65-70% range for success.
The other missing part of the equation would be what's the situational difference of making a kick in a comparable situation (i.e. high pressure situation to tie/win the game under 2 minutes or whatnot) as I'd hypothesize that you're probably going to see a below average performance in those situations as rushes are allowed to sell out in those situations (not worrying about the fake), extra adrenaline from the kicker may lead to a break down in mechanics, etc. Probably reasonable to think that you're looking at something like a 10-15% reduction in performance in those situations at minimum … which would bring the expected make % of a 38 yard FG in that situation to probably somewhere in the 60% range or so … which is far from a sure thing.
What's actually really interesting in looking at the stats you've provided is the difference between extra points and FGs from 0-19 as they are essentially the same kick with the exception of the hash marks being in play on the 0-19 kicks.
