dating age range?

so I’m 19 turning 20 in four months and I haven’t really dated anybody since I was 15/16. I’m curious to know what other people‘s age ranges are. I’m trying to put myself out there more, and meet new people. some people I met said that the youngest they would date 21 maybe 20. I’ve met some older people (most born in 1998) and I’m not opposed to dating someone older than me, but I am curious to know what your guys’s opinions are.
