Rainbow Trout in the Thames

How could I choose one person in a whole world of choices. Though to narrow it down for me, let's work it out.

• At 100% is all of the people over 16 and under 25 for a person like me who are not family because i'm not one of the characters from Game of Thrones .
• 50% of that are women and I like the opposite sex as much as you are insured that Bridget Jones is wearing her comfy granny pants.
• 10% that from that 50 are gay or count 
• 10% are married or are in a sort of relationship.
• 5% are popular people who would not look at me.
• 5% are popular people who would bully me or have bullied me.
• 10% are people around the world in countries I would never visit.
• 7% have already rejected me or have parted ways with me.

So in this world with 'plenty more fish in the sea'. I am limited to only rainbow trout in the thames estuary. I have a choice of 3% and I will only meet about 0.0002% of those men.

So when thinking with that formula added to my thoughts why is it that 3 men should come along at once?
