Yes, every video you download or stream is actually compressed quite a lot, the bitrate just determines how much compression is applied. Higher bitrate means the file is bigger and less compression is done, while low bitrate means the video has a lot less bits to store all that data and so has to do more compression.
Wikipedia has a list, it may not have every single one but it should have most of them.
