No worries. They're your friend for these types of server-related questions/issues/tasks.

These are SQL queries that you or your host need to run on your database.  If clicking fix it does not solve the problem, you need to run them via PHPMyAdmin or via SSH.

We use the calendar primarily to show when our members have a birthday.  Now the 'events' page does not reflect the member birthdays. 
The 'events' format may be more advanced, but it left out one of the calendar's most basic, and for us, important functions.

You would be removing the format="short" part mentioned above, but within the forums->widgets>forumstatistics template for that. 

Please note, we do not provide official support for customisation, so please ensure you back that template up before you do so.

I did the same as you and I'm also seeing the same issue. Changed the Forum Stats block from short to long format and now it doesn't refresh when the cache refreshes (ours is set to refresh every 4 minutes). I can get it to refresh if I edit and re-save the block, or if I delete and re-install the block using the Block Manager.
Does anyone have any suggestions to fix this? Please don't say revert back to short format post and topic counts 😬

It is a per user profile setting (per user) now:

Edit HTML theme and go to forums -> font -> index -> forumRow.
Find:
<dt class="ipsDataItem_stats_number">{number="$count" format="short"}</dt> Replace:
<dt class="ipsDataItem_stats_number">{number="$count"}</dt>
