Yes theres a big possiblity that some or maybe should we say ,almost everyone will use bitcoin on that time.because of some changes in the market. Cryptocurrency will rule on that year.
Well i think theres a difference between btc being the main currency in 5years and btc being used by most people that time. I think its the latter, meaning that by 2022, most people would've already been aware and in a way have used btc. I'm sure fiat would still be the top currency then but most people would likely have btc wallets already and have transacted one way or another using bitcoin
The user base of bitcoins will surely get increased by that point of time but its hard to predict that each and every one will start using bitcoins by 2022 as bitcoin is still new to many people and have not reached to each and every corner of the world and it will most probably take long time for that to happen.
What's meant here is that by 2022, most people have been exposed or have had contact with bitcoin or cryptocurrencies in general. Which is highly possible at the current rate of bitcoin usage. It doesn't mean that if most people have used btc, that they'll be using or depending on it exclusively
The number of people using the Internet is increasing, this can be a decisive factor for Bitcoin. But even so, it will be difficult to reach so many people in just five years, because there are many people who need to be educated about the different aspects that circulate this technology, such as decentralization, peer-to-peer technologies, blockchain technologies among others things.
Maybe not just in a matter of five years, but much more, the people would start to adapting to use bitcoin since everyone would be using it. That's how we are. What the society does, eventually we do too. It's not that hard to learn all these stuffs though since we learned it all by ourselves. We didn't even spend a whole night to understand the basic things about bitcoin. Maybe the whole concept of bitcoin, and the foundation of mining, trading, gambling, etc. and other stuffs about bitcoin, that would take a little while. But when it comes to just "using" bitcoins, it wouldn't take more than a day.
So you have suggestion that bitcoin will be used almost everyone in five years?I think there is no chance to it happen. I see the problem to that happen is that bitcoin limited by 21 millions and in fact it will be not enough for all humanity. But it's kinda the last problem of spreading bitcoin over the world. The biggest problem is that it stays many places in the world where there is no even a computer and bitcoin is impossible without internet connection. All that factors will disturb spreading of bitcoin. And I think the time when almost everyone will use bitcoin will never come.
Do you not read?

It's literally right in the start of my post.
The 21 million limit of bitcoin wouldn't affect the adoption that much since we can always have small denominations like 1mBtc, 1uBtc, etc. The scarcity of bitcoin would create value to it. If there was no limit, bitcoin wouldn't be this valuable or it might not even be valuable.
Simply take a look at the water, in places that are surrounded by the sea, water isn't expensive. You can get it easily. But in places like Dubai, water is valuable and they just don't waste it. They preserve it and at the same time the recycle water.
In the case of the people that has access to the Internet and those who do not, you might want to read about the
Digital divide. There are also proposals wherein they would launch hot air balloons (or some air stuffs) that would carry Internet/WiFi signals. That would allow remote places to have Internet connection but it also has its disadvantages like everyone being connected in the same network, etc.
