What Is Db Full Error?

If I try to create a table in mysql and the db is full what error will I get? I'm making a system where each table that grows gets a database and only that table. I'll query multiple tables for data. I know the table full error, but I'm not sure what error is returned if the db is maxed out of table space.

Is this the right way to look at it, or can one DB hold an infinite amount of tables until my Google Cloud Disk is full?

Removing empty space from database

Let me explain the situation.
Suppose I create a new table with an auto_increment column, and I make 3 new inserts in it.

Table: id, name
1, john
2, Alex
3, jeet

Then I delete the last record and create a new one.
Now, mysql will remove the entry at record id "3", but it will not add the new record at id "3".
The new record will be added at record ID "4".
So table will look like this:

2, Alex
4, Sam
