No I do not think that it will get used by everyone in 2022, we can also not predict this too but I do not see it happen..
I think we are still very far from it and there are a lot of other currency's too.
Other currencies were never a hurdle in the way of success for bitcoin, but still it does not seem possible that by 2022 everyone in the world will start using bitcoins because bitcoins is still too new and it has a long way to go still, it already spent almost 9 years and it is still not being used by a third half of the world.
Yes majority of people are not familiar to bitcoin yet and I don't think that in next 6 years bitcoin will reach to each and every individual across the globe, and even if it reaches its not possible that everyone will show their interest in using or investing into it.
