Correct!
'No ga' and 'no wa' have the same sort of effect as 'koto', making a verb a noun. Whereas Miru is to see, miru koto/miru no wa/miru no ga is seeing. To directly answer your question, 'no ga' made 'miru' a noun, adding 'suki desu' to it means you like it.
りんごを食べる。I'll eat an apple.
りんごを食べるのが好き。I like to eat apples.
One way to think about it is like adding ~ing to a verb. miru no ga = seeing, taberu no ga = eating, oyogu no ga = swimming, etc.
Someone smarter will be able to explain the differences/potential nuances of using 'no wa' instead of 'no ga', as well as koto.
