Do cell phones pick up information from other cell phones?

My one nurse that took care of me in the hospital , her profile popped up under my suggested friends on my Tik Tok? Do cell phones pick up data from other phones? Since she was a great nurse to me , I was going to follow her and thank her for all her help, Do you think that’s appropriate for me to do or do you think that’s weird? I am shocked she popped up as a suggested friend. What would you do?
