Without the error you got from the install of virtual box its hard to say why you need to run those commands.

The yum update command will ensure you have all the latest bug fixes and security patches installed.

The other 2 commands install packages that would be needed by virtual box to build the kernel modules virtual box needs to run, depending upon how your installing virtual box these dependencies would normally be automatically installed for you

yum install dkms && yum install gcc*
will install the necessary requirements to be able to build the VirtualBox kernel module, thus making the error go bye bye, thus enabling you to install VirtualBox.

yum update
this will update your system... a good idea to do regularly.. same theory as Windows Updates.

sudo yum may be the command.

In some odd deal the installer for both vmplayer and virtualbox doesn't seem to be written well enough. There are a few manual things you need to do and I can't say why other than the installer didn't install them. Then I think you will have to add your user to vbox users too.

Many apps seem to be a bit complex, even well known ones. Things like changing permissions to these add on files get kind of difficult even for me. You have to sometimes know how to ask how to find the correct issue too.

dkms is a package that tracks how your kernel changes. It is supposed to fix all your packages that need a correct kernel version and make changes.

Update is always a good thing since everyday there are changes. A new system install is not current for very long.

I think the installer needs the gcc for part of the install.

They really could fix all that. I guess they leave it in a generic form to save virtualbox people's time. They just have to create a generic version and let each distro fix their own stuff.
