Yes. Most of my watches have Rolex movements, so I am generally more familiar with them. However, these days, the cost & difficulty in sourcing Rolex replacement parts make Rolex movements especially challenging to work on. With the exception of the 775xs, once you acquire the skills & tools, I would say that servicing ETAs are no different than servicing Rolexes. They all work essentially the same way. It is more a matter of which movements you spend more time working on, so the process becomes more instinctive. Parts availability aside, if you have successfully overhauled ETAs, you should be able to do the same with a basic Rolex. But before attempting a Rolex, I would seriously consider whether you have the time, patience & funds for Rolex parts. If you lose or break a rotor spring or cap jewel or whatever, it will likely take alot of time, effort & money to find a suitable replacement.
