There are some non-obvious customs when editing answers, that's unlikely to go well as a very new user. But editing questions mostly for formatting and language is certainly doable without any reputation.

I'm assuming the edits are reasonable itself, there are some odd patterns that you see regularly like people using code formatting (monospace font) for emphasis. That kind of edit will get stopped.

Another option to get the basic SO privileges is to ask or answer on any other SE sites. There are many of them, and almost all are much, much easier to participate in.
