Is it possible that a 1 block shaft is generated in minecraft?

I recently started minecraft again (bedrock edition) and generated a new world after some time I discovered something strange. On the side of a mountain, a 1 x 1 block shaft was about 9 blocks deep. There was stone on the ground, I mined it and lo and behold, the shaft goes really deep. In addition to the shaft there was also a skeleton spawner and at the end a rather huge cave that also looked a bit strange. On top of that, a thunderstorm started when I wanted to go down the shaft. It all made it a little more creepy.

Now I wanted to know if anyone had ever seen anything like it. Oh yes, if you have the bedrock edition and want to look at it, the seed was: 1796559819 and the coordinates where the shaft can be found: -20 321

Seriously now: Such shafts can appear in seeds with a 5% probability

Phew I'm relieved Otherwise I would not have started minecraft again for the next few months ^^

No, you don't have to worry about that

I don't quite check

Yep, it can happen. But it is very rare.

Where did that go with the 5% ago xD
