No. It just depends on your community really.
Last year I was inactive for the majority of the year thanks to covid, but I still managed to amass 5k subscribers.
In 2018 I amassed 10k by not doing very much.
If you have evergreen content and have good search engine optimisation, and good calls to action, you can theoretically get more subscribers.
BUT remember user behaviour. If I find a video that's in my recommended, I might subscribe without even checking the rest of the rest of the channel. But if someone finds a video that's a year old, and that just happens to be your most recent video, that 1 year gap between videos could give new visitors a signal that you're no longer on YouTube and that there's no reason to subscribe or return.
This is why it's good to stay active in your community just to let people know you're still around.
My first videos that I've published after long hiatuses have always done surprisingly well, and even if they don't do well in views, they do well in engagement.
The algorithm follows human behavour. If humans aren't following your channel because you're inactive, then it's basically up to your evergreen content to do the heavy lifting.
YouTube just answered this:
The issue with this video is it only covers a 60 day period (Which you don't really want to be going longer than 2 months without content anyway) so doesn't take into factors those who take longer periods.
Also, if you don't upload for longer than 6 months, you also get kicked out of the YouTube Partner Program and will have to re-apply. I was concerned about this last year as I took a 5 month gap and was getting very close to the 6 month cut off period.
