Above comments are correct. Also sailing further away from the center seems to increase the chances of finding swamps with plenty of crypts. At least according to some anecdotes.

Not true in my case.
I play on a server with 9 friends so I wanted to find 'fresh' swamps and started near the edge of the world. Still no crypts in the first 5 swamps I found.

Well, it is anecdotal evidence so yea.

We had horrible luck at first finding crypts as well, 5 or 6 swamps with none. Then we looked at the opposite direction and found crypt after crypt from there, not even that big swamps either but they had 11, 9 and 10 crypts and were two minute boat trips from each other. So it's pretty rng heavy.
