is it possible for someone to be Forever alone for 70 years... if they proactively tried pick up?

I see tons of facebook videos of guys doing pick up, alot of these videos there is countless rejections

but occassionaly there is one chick who likes the interaction.

ever hear that saying there is plenty of fish in the sea? do you guys think if a forever alone participating in pick up culture they would remain alone for 70 years...?
