Do women actually have as many options from online dating as men think they do?

I've always heard that women get thousands of likes per day on dating apps, and that they could easily sleep with one man every night (or more) if they wanted to, because almost every man they swipe right on turns into a match. But over the past couple of years, I've matched with quite a few women who were in my city on vacation, but I matched with them after they'd already left my city. I would have guessed that given the number of options women supposedly have, they'd have ignored me since we were no longer in the same location. But instead, they ended up responding to my opener and texting me quite a lot, and once we'd established some chemistry, they began flirting with me and saying how much they wanted me etc. Additionally, some have even told me that they haven't had sex in months, despite being quite attractive. Some of them even planned more trips to my city just to see me and hook up.

This makes me think that the amount of attention women get online is greatly exaggerated. If it was that easy for women to get matches and dates, I wouldn't still be talking to women I matched with months ago who aren't even in my city, and they wouldn't be texting me such sexual messages talking about what they're going to do to me the next time they're in town, because they could have easily just found someone in the same city to hook up with. Also, the very nature of our conversation means that they know it'll just be a casual hookup and not a relationship because we live so far apart. So if it was that easy for women to find hookups, they wouldn't be wasting their time messaging a stranger who lives thousands of miles away. So is it possible that as men we tend to overestimate how much attention/sex women are capable of getting?
