Basically, be it USN or USMC, your fleet flight time is based off of readiness. Something I've noticed over the years is that, for a given timeframe, each community (VP, Helo, VQ, etc) tend to have the same number of hours/pilot after finishing a sea tour (or more accurately, a specific window of time, since USMC tours are a little longer). There are caveats, like Hornets, but let's ignore that for now, since your question is specific to helos.
Yes, there will be some that have more hours than others, for various reasons, but generally people come out about the same. Big-wing guys may have a little more nowadays, but they're still tied to readiness.
The Marines here can fill in what they're getting nowadays, but for the Navy side, expect around 800-900 TT and ~700 in model. If you go to the FRS, expect another 500-700 hours in model, depending on what's going on and how forward leaning you are. If you go to the HTs, and the birds aren't broken, 1K is attainable, but it will depend on how healthy the airframes stay.
These numbers are swags, based on what I'm seeing now. When I was a JO, the numbers were higher, but we live in a different environment now. Given where you are in your "career," these should be close enough, at least on the Navy side.
