The odds

A bitaxe has a miniscule chance of finding a block. The one found in July might have been running 5-6 bitaxes 2TH/s. The recent one was probably not running bitaxes as it was something like 30PH/s. They just got lucky solo mining.

If you're using an old laptop it might be something like a trillion to one odds. Use it to run a node or a nostr relay. You need something more powerful to mine bitcoin.
