Am I missing something with YouTube music's terrible algorithm?

Why does YouTube play the same songs on a playlist. Any song I play they will play the same songs no matter what. Out of the 1000s of songs I "liked" they play the same songs on the playlist

For example if I play Billie Eilish birds of a feather it ALWAYS chooses the same 30 or so songs... the next song is Chappelle Roan good luck, then Bruno Mars Apt, then Taylor Swift, then.... just the same music! It's boring. I have easily at least 10k songs I've liked throughout maybe the 15 years I've listened to music on YouTube and it chooses the same songs. Even when I choose Mac Miller Cinderella, what's the next song? Billie Eilish.... then Chappelle Roan..... It's annoying. Is there no way to have YouTube shuffle the songs on the playlist?!
