How come the total number of votes on a TV show or TV Episode or Movie I vote for never changes once I cast my vote and rate a title. If a TV show or movie has 100 votes and I rate it the number of total votes NEVER changes, even after I rate it and refresh the browser or even do a hard refresh the total number of votes never changes. I have watched it on over 50 different titles all with over 5 votes, all of them I refresh the browser and it doesn't matter how many votes it has, 100 or 1123 after I cast my vote and rate the title and refresh or hard refresh the total number of votes always remains the same every time.

Votes are not counted in real-time. From https://help.imdb.com/article/imdb/track-movies-tv/faq-for-imdb-ratings/G67Y87TFYYP6TWAV (see bold highlight)

How do you calculate the IMDb rating displayed on a title page?
We take all the individual ratings cast by IMDb registered users and use them to calculate a single rating. We don't use the arithmetic mean (i.e. the sum of all votes divided by the number of votes), although we do display the mean and average votes on the votes breakdown page; instead the rating displayed on a title's page is a weighted average. To display the detailed votes breakdown, click the number of votes located directly below the average IMDb user rating. For an example, see the User rating breakdown for Inside Out.
The IMDb weighted average does not change upon receipt of each new vote, but instead is updated numerous times per day.
A TV series rating is not the weighted average of the ratings of individual episodes. Instead, customers vote separately for the rating of the series as a whole via each title’s series page.
However, votes are logged in your ratings history in real-time so you can always visit http://www.imdb.com/list/ratings/ to confirm receipt of the vote on IMDb.

Thank you for your helpful reply. The bold highlighted section you refer to states that the weighted average rating does not change upon the receipt of each new vote but gets updated numerous times a day. So, I believe you are saying, this means that not only does the weighted average rating not change as each new vote is received but also the actual total number of votes received displayed below the current weighted average rating does not change each time a new vote is received but only changes once the weighted average rating is updated. At that time the total number of votes received displayed will change to reflect the total number of votes received at the time the new weighted average rating currently being displayed was calculated to show the total number of votes the current displayed weighted average rating was based off of. 
This makes good sense thank you for pointing it out as well as the way to check my own current ratings history in real time to see if my vote was received.
