Personally dont think that's a good comparison. I would say it's more like taking a photo and claiming you know how to paint. You're still actually cre a ting something, but using a digital tool that does it for you. You chose the subject and fiddle with setting to get a better image closer to what you want and then can take it into software to edit it further.
Its art in its own right, but you shouldn't directly compare it to painting.
I think my analogy is more accurate
