Is it weird for a 17 year old to be friends with a 22 year old?

I made this friend at church. We are both girls and I just am making friends because I suck at it and feel like no one likes me. Self issue, I know. But the thing is, she is like about to be I think a senior in high school so probably 17, and I’m 22. Is it weird to be friends? it’s obviously not a dating situation so is it bad to be friends? Is it weird? What do I do? Will she think I’m creepy? I would have never spoken to her, but we sit on the same row usually and she’s always watching me so I don't know if she just needs a friend, was nosy, or what. There is like no one else there our age so I don't know. I always wanted church friends my whole life, but no one was my age or they had their own groups. I just came to this church and so maybe she feels the same and just wants to be friends? I don't know I don’t mind being friends, I love making new friends but i don’t want to be creepy bcs I am 22. Or maybe she’s just nosy? I don't know help lol
