DeGoogle Yourself

Like the title says. I've been reading recommendations about this OS, so i went to look on their homepage, but you can only install it on Pixel phones, which are from google, right? In other words, to get rid of google products, you still have to spend your money on google? Am i missing something? I thought there were other custom roms where you can choose whether or not to add to add google products? Please be gentle, i'm a noob when it comes to custom roms. I have had CyanogenMod on a phone many years ago, but someone helped me do it. And i'm really not current with changes in recent custom roms.
