questions about very low count in distrokid

i do not quite understand how the count is done in distrokid (or youtube misreported? ) , take one song released in Feb 2024 for example, it shows total 54 plays (50 out of youtube music, 4 from content id on one youtube video) , but when i see number of play in youtube music is shown as 654 times, and youtube video is 535 views. any idea why it is low in distrokid? thanks for your help!
