There are several types of ads that may appear during or next to your videos when you've turned on video monetisation.
The table below reflects ad options available in YouTube Studio, where you can control placement of ads to appear before ('pre'), during ('mid') or after ('post') the video.

Ads outside the video player
Watch feed ads (which include display ads) are ads that appear in the feed of recommended videos below the video player on mobile and next to the video player on desktop. These types of ads cannot be controlled from within YouTube Studio.
Also referred to as ad pods, two back-to-back video ads can occur when you turn on skippable or non-skippable ads on your video. This kind of ad format is only displayed on longer form video content (at least 5 minutes in length) on the platforms mentioned in the table above.
Ad pods help reduce interruptions for viewers of longer videos, resulting in a better viewer experience.
Ads on shorter videos
Video ads may be less likely to serve on very short videos. This practice helps to better improve overall viewer engagement and revenue over the course of a viewer's session on YouTube.
