Yes it is. But don't even try to think if you go in that luck is your too.

The answer for your question is ... the mythical, magical, superstitious, evangelical, holy molly guacamoley RNG .. Before spending in the events where you have to be lucky, you need to perform several task first .. First one is to open up *tar and offer something sweet, something colorful and nice .. then pray :

Our Father, who art RNGesus,
Fickle be thy nature.
Thy drop rate rise,
The crap drops cease,
In our attempts, as well as in our free draws.
Give us this day our daily jackpots,
And forgive our disbelief,
As we forgive shinobis who discourage faith for thee,
And lead us not to bankruptcy,
But deliver us rarity.
For thine are the game mechanics, and the power, and the blame,
For ever and ever (Until the weekly reset).

In the name of the Village, The Hokage, and The Holy Goats.
Amen.
