So anything works in solo queue. Yes, we know that. ;p
First, this. Kind of sums up the second half of your post.
Second, what works at high-elo will always work at low-elo. What works at low-elo will not always work at high-elo. Sometimes, things that work at low-elo will out perform things that work at high-elo in a low-elo situation (Viktor, for instance, or Akali). So reading tips from pros isn't bad. You just have to remember that they are better than you. For instance, in Nyjacky's guides on lolpro, when he mentions Rod of Ages, he says that if you don't have it by 13 minutes, you shouldn't ever go for it. He says that he usually has it around 11 minutes. Things like that are important to note.
Third and finally, pros with those mechanical skills can make things work that otherwise wouldn't, because of their mechanical skills (Voyboy). Lulu top feeds more often that it goes even or wins because she's extremely squishy early on and lacks strong escapes. Champs that can start dunking on her at level 2 will get fed beyond belief. That said, Lulu top with the skills to not get caught does pretty well for herself.
This is why low-elo players shouldn't play high-skill cap champions unless they are just playing for fun. For instance, Orianna is a very fun champion to me, but I rarely play her because I know how hard she is and how I'll be able to do better with an easier to play champion like Diana or Akali. I would put Viktor in this category too. He DOES work, but it takes a lot of skill to do it well, and an easier to play champion could shut him down early (Fizz, Akali, Diana).
As far as Viktor being bad, he is the least played mage in the game, and I believe he's the only one to have not seen a single game in the LCS. Even Ziggs and Zil mid have been seen at least once. Viktor is just slightly underpowered and the pro's aren't going to waste time learning every in and out of him until he isn't.
The underlined portion is wrong, Viktor was played in LCS, I can't remember if it was Complexity, or MRN though, maybe even Vulcan.
Also, pretty sure Xerath is the least played mage.
Viktor himself isn't underpowered, his lack of a true sixth item slot is what makes him weak (doesn't really matter until you get to full build status anyway)
Some professional players do know the ins and outs of him, he's not a hard champion to understand by any means. Viktor isn't super high-skill cap, he's closer to average than you might believe. Just gotta land gravity field which is easy, and properly aim his death ray which is pretty easy after you use it for a game or two.
