I was trying to find limits of Rest API calls an org can made in a day.
This article 'API Usage Limits' helped me until a particular line confused me which says
Any action that sends a call to the API counts toward usage limits, except the following:
1.Outbound messages 2. Apex callouts
I'm making a Rest API call (to same org although) which I think, could be referred as 'Apex Callout' also.
Would it counted for API limit(max 1M for enterprise edition as per article) or not or am I missing something ?

Every inbound call into the API counts against your 24 hour limit - note: the limit is per 24 hours, not per day - the difference is that if you make 10,000 API calls at 10:01 GMT today, those calls are removed from your count at 10:01 GMT the next day, not at 00:00 GMT. A small, but important thing to remember.
So, if you made a call out back into your own org (I am not sure if that would really be the best way of doing this as I would rather have one class that handles the data coming in via a REST call that then hands the processing off to a common function so that other process (such as where you are doing the callout) handles the real work, so you avoid the expense (time/resources) of a REST call), the incoming REST call would count againt your 24 hour REST limitation.
