Not a native English speaker, but when I hear "thankfulness" I kind of hear "to someone/something" (not that much for "gratitude"). Now "humble" I resonate much more with, but I don't see it connected to "thankfulness". People can be "thankful" to someone and feel very entitled at the same time.
Humans have been fighting against "chance" for the whole evolution (chance of starving if you don't catch something, chance of suffering if you take a bug, etc.). I fully agree, you should not feel responsible for it, but you should not like it (or thank it) either.
