Worse, it was just almost all horses. There are a few in Central Park pulling tourists and that’s enough for the Pollyanna’s to point to and go “See! We’ll be fine!”
The number of horses in the US is down by about a factor of 3 from the peak in 1920. They're mostly recreational now though.
Presumably you are a human, not a horse, yes? Presumably there is more to your life than dragging around carts all day every day?

Horses where the plaything of the rich. Farmers were using oxen not horses for the most part. However the modern plow (invented in the mid 1830s - John Deere being the best known inventor, but others were inventing them about the same time) needed the faster speed of a horse to work well, but if the previous farming technology worked for you then oxen (or donkeys ... - there are several other work animals used in different areas for farming) were better.
There are likely more horses today than there were in 1900 - but now they are play things for the upper middle class living in the exurbs (commuting via car to their city job). Sure there are a few Amish (and other similar groups) making a living with a horse, but most of them are toys for the wealthy.
