You don’t have to be an expert, or really even remotely knowledgeable to create a community. If you want it (and whatever instance allows you to create a community), you can make it. Where the challenge comes is in growing the community. You’re going to have a hard time attracting people to your community if you don’t have anything to offer. A community that’s entirely composed of you asking questions nobody answers isn’t really of interest to most people.

What I recommend is that you fine one or two people who you think might fit the community’s needs, and reach out to them. See if they’d be interested in creating content in your community. I did this on reddit with a couple small communities I made. I sent DMs to power users in similar communities, and asked if they’d be interested in joining a new one, in exchange for giving them mod and letting them have some control over the direction of the community, while I did most of the busywork.
