Since you said you're new at editing, I hope you won't mind me explaining some things to you ^^".

Rollback means that you will undo the edits of one particular user, regardless whether or not they made consecutive edits (you can rollback one or one hundred edit of the same user, as long as no other user has edited in the meantime, as the rollback will stop the moment it'll find an edit of another user).

If multiple users have consecutively vandalized a page, the rollback tool essentially becomes useless as it'll just revert the edit of that last person. What you can do in that case is go to the history section of the page in question (click the arrow next to the edit button to have a roll-down window appear and select "history").

The history page shows every edit ever made to that particular page. Before every edit, you'll also see "(cur | prev)". Those two options are quite handy, both to combat vandalism as to maintain your articles. The "prev" is short for "preview", meaning that if you click that option, it'll show you the edit made by that particular user. This will let you know whether one of the many users that made a change to your vandalised article, was one of the vandals or actually someone who tried to make a good edit in between. The "cur" option on the other hand stands for "current" and it will allow you to show multiple edits as one. By clicking "cur" in front of the last edit that you believe to be good, it'll show all the changes made to that page from that moment onwards. As such, you can see perfectly well what has changed (which is also a handy tip for basic page maintenance, as you can see in one go all the changes made to a page as opposed to having to review every edit made one by one) and because all the intermediate edits are then showed as one edit, you also have the option to click the "undo" option and undo them all in one go. This is very handy when multiple users have vandalised the same page.
