xQc's Law 

xQc's Law (sometimes referred to as Lengyel's Law) states that there is a direct correlation between surface village location in terms of x and z values and probability of sub-surface lava spawning in the respective chunks located at those x and z values. It is implied through xQc's Law that lava is less likely to spawn at y values near y = 11 when in chunks containing a surface village or near a surface village.

XQC's LAW 

According to XQC there will be no lava pool underground 50 blocks away from the village. All lava that is in bedrock level does not count.

You will not find a lava pool underneath the village because of XQC's LAW.
