Do I need to get better at approaching people at social gatherings?

for example, if I’m at a Christmas party or if I’m at an event for singles, I am afraid to talk to people first sometimes because I know most of them were going to turn out to be jerks to me. Do I need to get over that fear And go for it? I guess if they don’t seem in to me after a minute or two I would just move on I don’t know. It’s pretty obvious if responses are short and they don’t ask you questions back. but then it’s like do I just go from girl to girl at these things? And if they’re not alone, it gets harder.
