There's a general rule in all startup businesses (and that includes photography): expect to make a loss for the first two or three years while you build up sufficient market visibility (and for a photographer, reputation) so clients are directed to you by former clients or by your marketing material (or both).

Your belief in your own ability as a photographer is only a fraction of what is required to get a business up and running.

So comparing your new business to that of established photographers in your own market will be meaningless. Concentrate on growing your business using the right business approaches for your area (and your skills in business), not on comparisons to other people. Established businesses have invested a lot (years) of time and effort into being visible and respected. The survivors are very good at the business of photography, not simply photography.

Accept as a given that some photographers, typically the best established in your area (and the best at business, not necessarily the best at photography, although that helps), will be doing more business than a new entrant.

And, honestly, your core market research in your area should be giving you answers to questions like the ones you asked. It's going to be different for everyone. You need to get a feel for your local market, not what's happening on the internet, and only you can do that.
