With this little function, you can understand what looking at does:

Write a word in scratch buffer and leave point at end of word, then do
M-x test-looking-at

Then put the point at the beginning of word and run again test-looking-at

,----
| (defun test-looking-at ()
|   (interactive)
|   (if (looking-at "\\>")
|       (message "There is nothing after point")
|       (message "there is something after point")))
