Jerome Gambit: Warping Players' Minds?

Recently I watched a YouTube video by Chess enthusiast titled "Most bishops aggressively attack - Jerome Gambit".

The video showed a game played over-the-board, and I took notes: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Nc6 8.Qxc5 Qe7 9.Qd5+ Kf6 10.Qf5#

The line looked familiar*, but when I checked The Database, it turned out that it had only a couple of examples.

So, I went online and checked out the games at lichess.org.

I noticed in setting up the board there, that as I entered 9...Kf6,  lichess.org indicated that it had 11 games with that position. It also indicated that from there, White scored 64%.

Only 8 of the 11 games were available for viewing and download. Being naturally curious, I calculated that the average rating of the players with White was about 1465.

Then came a worrying thought: Does the Jerome Gambit warp players' minds such that they can find a checkmate-in-one only about 2/3 of the time? 

Certainly there must be other factors in play!
