Were they hitting on me?

At work, a guy walked up to me gave me a fist bump and told me I was so pretty. He never flirted with me, he just diverted his attention toward my other other coworkers next to me, talking to them. I've also had another guy who seemed bored talking to me, ended up calling me a beautiful girl loudly in front of everyone. Prior to this, no flirty energy. I've had another guy who said I looked cute and he didn't know why I could still be single. I honestly have no idea... people just compliment me but never show any interest in me.
