Yeah that's a good start Daz Studio doesn't require a beefy computer, just start posing with the base models that comes with it. Learn all the functions, familiarize yourself with all the different panes and follow beginner tutorials on youtube.
When you start rendering then your pc specs will determine how good of a quality the final image will be.
UncleFredo NO, the pc specs does not define the quality. The specs define only the time time it takes to make a picture of good quality. Rendering is like photography. You compose a picture and some are better at that but you can learn how to that. Tutorials about the functions of DAZ helps witch the technic like in photography learning what are the whole functions of a DSLR for. But other tutorials are needed after you know the tech. Like how to design a picture, how to use colors, light, effects etc to have a specific atmosphere. On youtube you'll find Jay Versluis the WP Guru

The specs of your system only define how long it will take to make the pic. You can render the same pic in the same quality on an potato system or a high spec system. The only thing that will stop you rendering is if your system doe not have enough resources, mainly RAM. If all graphical components (textures, shaders, objects etc) of the whole picture do not fit into you RAM you can't render it and DAZ will crash. 32Gb RAM should be enough for the time, but better for the future are 64GB. Every other component of the system only defines how long a render will take. The biggest impact has the GPU. No NVIDIA-GPU and the system will use the CPU to render. Even an old GTX1070 renders faster than the fastest CPU if the pic fits in the GPU RAM. After the GPU the CPU is important, a fast multi core CPU will make a faster render. A realistic iray render that takes little time on a RTX3090, will take more time to render on a GTX1070 and much more with the CPU only. The result you'll get will be the same in all three cases only the time you have to wait for is different.
