Solo mining as node vs Solo through Pool

I understand that true solo mining requires setting up a node. I’ve looked into it and it seems like a little bit of a hassle to setup. Solo mining through a pool such as 2miners is not true solo mining and is more of a convenience thing.

My question is: are you more likely to solve a blockchain using a node compared to using a pool? I don’t understand exactly how pools function, but I would think there would be more latency because the pool would act as an extra step in the process. If there’s more latency, I would assume it would be slightly harder to solve a blockchain. Please correct me if I’m wrong on that logic.

Besides that, I don’t know what other downsides the pool would have besides the fee they take. I personally don’t care about the fee at the expense of convenience since I have a pretty small setup. My rig consists of (1)1650s, (1)3060, (2)3060Ti, and (1) 3070. Total hashrate 125MH/S.
