Why need a really big storage to download? – GarageBand Review

Why do I need a big storage or even more space to download this app? Because I’m a little confused because I’m tired of having to delete stuff in order to have this app. Like I had to delete some photos apps Messages etc. Just saw that I have enough space to download it,but girl. It.still.needs.even.more.space!!! Like why need a hella Big storage when it’s literally just an app? I remember when trying to reinstall notes and it didn’t require much storage and why can’t it have the same thing on this? I kind of feel stupid writing this because I feel like I’m making a bad mistake but i’ll just probably not do this ever again
