Pandas throwing "Error tokenizing data. C error" while loading data sets from URL
The path that you are accessing from is a Github repository page which is a webpage, it does not return CSV. You have to click on 'raw' option in Github and then pass the URL which in your case is:

test = pd.read_csv('https://raw.githubusercontent.com/oo92/Titanic-Kaggle/master/test.csv')
