You should always erase the drive and reinstall macOS when buying a used computer unless you purchased it directly from Apple. Depending on the age and whether OSX 10.12.4+ was used, you may be able to use Internet Recovery Mode to erase & reinstall macOS using Command + Option + R.
This is what the seller should have done before selling the computer:

How were you doing this? You need to follow the correct procedure for this. This may depend on what version of macOS you were using.
Get the Mac to set up an additional administrative account. This will work in all releases of Mac OS X so far.
You need to get into single use mode for steps one and two that are listed below. Start with your computer power off. Hold down command-s. Power on your computer. Continue holding down command-s until you see some text on the screen.
This page will give more details on how to get into single user mode.

Type in the following:
The first two commands will depend on your release of Mac OS X. Look at what is typed out in the console to determine the exact format. You do not need to type in the lines beginning with an ampersand, #, they are comments.
# Type the follow two instructions to access the startup disk in read/write.
# Press return after each command.
# in case of partial success repeat this command until errors go away.
/sbin/fsck -fy
/sbin/mount -uw /
# Get setup to activate a new administration account
cd /var/db
pwd
#List all files. The l is a lower case L.
ls -a
# The move command acts as a rename command in this format.
# In Yosemite, this file is zero bytes.
# the disappearance of .AppleSetupDone causes a new administration account
# to be added the next reboot.
mv -i .AppleSetupDone .AppleSetupDone.old
# reboot your mac
shutdown -r now

Check the links I provided in my previous post as they contain steps to reinstall macOS without any CDs since macOS has not been released on DVD for many years now.
If you follow the advice of @rccharles, you will be able to force macOS to run Setup Assistant again which will walk you through creating a new admin user.
You can also boot into Recovery Mode using Command + R as suggested and launch the Terminal app from the Utilities menu and run the following command:
resetpassword
Once you can log in again, then I would suggest creating a bootable macOS USB installer just in case something would go wrong with Internet Recovery Mode after you erase the drive.

I don't understand.
Start with your computer power off. Hold down command-s. Power on your computer. Continue holding down command-s until you see some text on the screen.
You did follow these instructions exactly? The Windows key is the command key.
You can do the same thing from Recovery mode.
some drill, but use command + r
( I think you have the option of command + r. some older machines do not have option. )
R
