What are the odds?

So I've played roughly 500 games in the last 5 months or so. There are a few opponents I've played twice..... but there's one guy I've now played 6 times. With the millions of players on here, that seems "out there".   All my games are 60 min. rapid, and I have it set so I play opponents within 200 points of my rating. 
Is there some reason, beyond coincidence, that he and I get matched up so frequently?

Just don't mess with his girl, if you're Rick, unless you're Ric.

I run into the same names in the 1200-1500 bracket tournaments.

I am guessing 60 minutes is a small segment that there I am not surprised. Timing makes a big difference too.

I would like to know when the “easier” games are at?

Kind of like poker, the late games with drunks are the money games not earlier regulars who are tough and tight.

The odds are higher if you play a certain time constraint since both wants to learn a longer time control.

You play a time control that a small portion of the users use so you may get the same users at a higher frequency than others

When I look at my stats, it tells me that there are roughly 2 million players on c.c that are rater higher than me. I have assumed that was just players in the rapid time control. Is that not true? That would mean there are more than 10 million players. So it still seems unlikely that I'd pull the same opponent multiple times randomly. 

Rapid is considered anything higher than 10 minutes 60m is a time control most people dont do 90+% of rapid players do 10+0 and 15+10 some fo 30+0 but 60+0 is a time control most dont play so thats why i said it was low users

~80 % use 10+0, minority uses 10+5, 15+10, 45+45 and 60+0

theres a decent amount of 30+0 players too

10+5 15+10 are a large minority 

15+10 is up there yeah, but 10+0 is above all else for rapid

"With the millions of players"
++ There are not millions who play at the same time as you, play the same 60|0 time control, and the same rating within +/- 200.
If you were to play sometimes morning, afternoon, night, play a popular time control like 10|0, and set a ratong range of +/- 400, then it would be less likely.

That brings up another question..... when I apply the math to what percentile I'm in and what my actual numerical standing is, it tells me that there are 12 million players in my group.  
I'm not sure what group that is. All my games are rapid / 60 minute games, so is it the group of rapid players, the group of 60 minute rapid players, or .......? Certainly 12 million can't represent the whole universe of chess.com players, can it?

I was paired with the same guy 6 or 7 times in a row on lichess. No, I was not sending him a rematch, nor he was sending me rematches. We just got paired 7 times in a row.

If you don't believe me I can send you the links to games.

Of course I believe you. I think after 3 in a row or so, I would have politely refused more rematches....depends. Hopefully, you were evenly matched and had interesting and competitive games.

Yes, he won 4 to 3, in fact, I had a winning score against him all along (1-0, 2-1, 3-2) and we kept getting paired (I wasn't sending him rematches, he wasn't sending me rematches, I would click on new game and get paired with him 7 times in a row). The first time he took the lead (4-3) we were no longer getting paired, I clicked on a new game once again, but this time I was paired with someone else.

I have no idea of how Lichess works....I assume similarly to chess.com. Looks like you're a rather highly ranked player, so maybe there aren't a lot of players at your level? That seems unlikely, but so does 7 in a row......

lichess has like 5 users so im not suprised

~35 thousand * average 

The 60+0 pool is relatively small, so if you have anything range there’s a good chance you could get paired more than once
