And if you are into stats, your chance of winning a block reward solo mining is infinitely higher than with a pool
That doesn't sound right, judging from how many users tell you that the chance is only around 2% within a year. Not to mention the difficulty is going to fluctuate, and I bet it will increase and just lower your chance even further. Doesn't really matter whether you have free electricity or not if you will never get it in the first place. Can you show us the math?
Based on my experience, I only saw one post from a lottery miner in this forum, while the rest are just talking about probability, etc. Most of the time they are just doing it for fun, so if profit is your goal, mining with a pool is arguably more profitable & efficient. CMIIW.
You misunderstand his statement. Here is another way of writing what he said:
If I mine on a shared pool my odds of winning a solo block all to myself are zero.
If I mine on a solo pool my odds of winning a solo block are unlikely but far far better than zero.
and another way would be.
you can't win a solo block on a shared pool. since you do must share with the other miners.
in a way he was being a bit sarcastic with his statement.

Shared pool by definition means shared odds of winning a solo block are impossible.
Mining solo means you take it all no sharing. It is unlikely to win a block but you can win one or more every day you point gear to a solo setup.
off topic:
I mine at a small pool with a password to mine only.
https://pool.laurentiapool.org/#/work146UJM5kgzLVUV23CXCf33KQKHckoX1gx3 will get 2.19 coins if we hit a block
now the pool has 222th which means $15.55 in earnings a day if it was not solo. a block is $132,000. so the shot of us hitting a block is 8500 to 1
but even at those odds it is not a solo block it would be shared with 4 miners. Its close to solo for 3 of the miners the rewards are very nice, but it is not solo and at the moment it can not be solo for the next block since 4 miners have shares and will get some of the coins.
