How come girls’ automatically assume guys’ that say they like younger girls’ are talking about girls’ way younger than her?

Now that I am 48 years old and single , I been meeting and talking to girls’ in their late 20’s and 30’s and early 40’s that assume when I say I like younger girls’ she automatically assumes younger than herself , when I am really saying I like girls’ younger than myself , , so now I just say , your age is fine with me 😂 Why do people always assume the worst case scenario , it cracks me up
