Is texting new college batchmates a bad sign on whatsapp? Am I bad person or should I change myself?

Since our colleges are currently going in online mode. So our subject teachers made a whatsapp group. From there we had access to almost everyone's number. Am i being creep or weird individual by texting random persons in their dm in a hope of getting notes or important information also who knows maybe a good friend.

When i text boys i dont have such feeling of weirdness or so but when it comes to girls i often wonder have i crossed a line or am i showing too much of closeness while texting them.
