My apologies in advance if my question sounds primary, I am very new at QA and Selenium.
What is the exact difference between:
wait.until(ExpectedConditions.visibilityOfElementLocated
(By.xpath("//a[text()='Show advanced settings...']"))).click();
and
wait.until(ExpectedConditions.presenceOfElementLocated
(By.xpath("//a[text()='Show advanced settings...']"))).click();
I had a look at here but did not figure it out.

use presenceOfElementLocated when you don't care whether if element visible or not, you just need to know if it's on the page. use visibilityOfElementLocated when you need to find element which should be also visible.
In order to declare explicit wait, one has to use “ExpectedConditions”. The following Expected Conditions can be used in Explicit Wait. To use Explicit Wait in test scripts, import the following packages into the script. Then, Initialize A Wait Object using WebDriverWait Class.
Expected Conditions in Selenium WebDriver provide conditions that are frequently used for automating test scenarios for Selenium automation testing. Like other Selenium language bindings, Expected Conditions in Java provide ways through which you can realize Explicit Waits in the test code.
We can also confirm if an element is visible with the help of isDisplayed() method. This method returns a true or a false value. In case the element is invisible, the method returns a false value.
The visibilityOfElmementLocated checks to see if the element is present and also visible. To check visibility it makes sure the element has a height and width greater than 0.
The presenceOfElementLocated just checks the dom to see if it can locate an element no matter its visibility.
