This is a long-known phenomenon: A difference between the putts indicated on the scorecard and in the in-game stats.
It concerns off-green putts as well as wedge shots on the greens. The scorecard counts them as putts but the stats don't. I suppose that the overall players' stats receive their data from the latter (but who knows?)
Alas, this is another difference:
Robert1893: for 3 putts or more, it lists 3.
It may be like this on a mobile device, but on PC, I see "5 putts" indicated after five-putting, both on scorecard and in stats. Of course, this contributes to the "Three putts or more" stats.
