Tyloo didn't get lucky.
It's G2 that made very bad decisions over and over.
Have advantage, let's push or peek CT or Jungle 1 by 1.
Molov CT, smoke connecter, don't plan the bomb and wait for it to go off to take duels, 1 by 1 again.
Got 2 kills short B, peek connector and A 1 by 1 to even it.
They peeked solo with no trade fragging potential, either pop flash.
There is clear lack of fundamental teamplay there.
At this point there is just lack of effective methodical understanding of meta.
You cannot play like in 2015 anymore.
