Server market has been quite saturated for a couple years now. It's not impossible if you have a good server with a unique idea, but don't expect to grow quickly.
Also, if you're looking to make money from it I would not advise it. At that point you're making a server for the wrong reasons and it will be far more difficult to create a successful server, especially considering the blockages to payments the EULA has now. Prior to the EULA, I made a decent amount of money for a short while, but afterwards it became difficult to even have enough to pay the server bill each month. Be prepared to pay the server bill out of pocket quite often, but don't let that discourage you from starting a server. It's incredibly fun to do, but also frustrating.
If you have any questions/want advice don't hesitate to reach out. I operated a small network of my own for six years, and have been on the staff team of countless other networks/servers.
