Apparently a solo miner using a Bitaxe mined their
first block today:
Your screenshot in the OP showed 55 kH/s. The one that found the block has 300 GH/s. That's already 5.5 million times faster. The total Bitcoin hashrate is
650 EH/s. That's another 2 billion times faster. So let's say 1000 people run a 300 GH/s miner for a year. That makes the chance of one of them finding a block 1000 * 365 * 24 * 6 (blocks per hour) / 2 billion = 2.6%. The chance per person is 0.0026% per year.
The whole ckpool.com has roughly 200 Ph/s of power:

In the public-pool.io there are 1,400 such machines operating:

This adds to the 45,000 operating.
The hash power in the OP is referred to the nerdminer, which is based on a generic CPU. The 300 Gh/s is probably a BitAxe, a machine built over a single ASIC chip of a s19 (so, effectively a 1/300 of a S19 minus some efficiency optimisation).
