I realise that the way that Toronto has started this series must be painful for you but nobody is reading much into one game. More pertinent are the following:

1. The Leafs reached the playoffs because they finished the season strongly and won when it mattered. That wasn't a fluke. 
2. The Leafs points total was not a fair reflection of their actual abilities. They only had one shootout win all season and would have been better than a wildcard team with even average luck on the front. Some of the  best shootout teams were the worst at ice hockey. Check this out:

The first and third best shootout percentages were owned by Detroit and Arizona. Other teams that did well were Vancouver and Winnipeg, neither of whom made the playoffs. Toronto were dead last.  If this doesn't show how ridiculous it is to award the same number of points for winning a shootout as for winning in regulation, nothing will.
