Bypass activation lock

Starting with iOS 7, deleting an iCloud account or restoring a device requires Find My iPhone to be disabled. Find My iPhone, in turn, requires the user to enter the password for the Apple ID attached to the iCloud account. This system ensures that phone thieves can't remove the account and avoid being tracked through the Find My iPhone website.
Unfortunately, there's a pretty easy way to bypass this requirement, as demonstrated in the video above. To do so, you first need to tap both "delete account" and the switch to disable Find My iPhone at the same time in the iCloud settings panel. That's actually the hardest part of the entire process. When prompted for a password, hold down the power button and shut down the phone.

When you restart the phone, you'll be able to go into the iCloud settings panel and remove the account without being prompted for your password. After that you can plug the phone into iTunes and restore it with no problem. Not only that, but because Activation Lock requires Find My iPhone to be enabled, that feature won't kick in after the phone is restored.
In short, whoever has your phone has just bypassed every possible method you had at your disposal to locate it again. The good news? Putting a passcode on your phone (especially with a short timer) prevents anyone from getting into the iCloud settings at all.

My iPhone is locked by iCloud, and I have seen many tutorial videos and they recommended this page to me https://bit.ly/2DbIzGu and I could not do anything I can do?

I was searching the internet and could not find anything on this. Best thing I would suggest is call the person you bought the phone and have them give you that information and then you can go through the steps to changing it.

There's a couple possibilities. Do you have an Apple ID and can you just log in with that? Or is it popping up with someone else email/username?

If Find my Phone is disabled (as it should have been in order to sell it) you could also put the phone in DFU mode and install a new IPSW (OS) file, which would overwrite everything and make it as if you were taking a new phone out of the box, software wise.

You really bought a phone that is locked. Perhaps even the owner does not know you have it.
Only the person with the Apple id, ending with .mac.com knows the password. If he is willing to give you the Apple ID and the password, this phone was setup with, you can unlock the phone. If not, you won't be able to do so.
I don't want to frighten you, but most likely you bought a stolen phone.
The security in that phone is so good, nobody, till now has broken this.
