Not on Bedrock, which the OP is most likely referring to; in that version strongholds do in fact often generate under villages, otherwise, they are more or less random with strongholds spread across the entire world, unlike on Java, where they generate in a limited number of rings around the origin with no connection to villages or anything else (based on the number of results for a stronghold below a village in Bedrock it appears that the game is actually coded to make them generate that way, not just due to random chance; of course, not every village has a stronghold and vice-versa). Either way, the easiest way to tell without eyes of ender is to dig down from the village well (or whatever is now the center of a village):
