What to expect when open to all ages

Hello, I am a 30 year old single female about to begin my fostering journey. I will be able to foster up to 5 children at a time, ages 0-16/17 including sibling groups, any race, gender religion, sexuality, etc. I am willing to adopt a teenager, but I would also love to adopt a younger child if possible. Will being open to fostering older children/ teenagers decrease my chances of getting placed with babies/young children? I am asking partially so I know how to decorate the last bedroom but mostly so I know what to expect so I won’t be possibly disappointed in the future. Thank you!
