Well, it's only day 1, so don't get frustrated yet. We didn't potty train our daughter until she was 3 years 8 months so you are not "too late"...it's not like there's a whole slew of kids out there that are not potty-trained because their parents missed some magical window of opportunity.
Emotionally, she just might not be ready. If she needs to be potty-trained to start preschool in the fall, and you don't get anywhere after 3 or 4 days, take a break, and tell her you will try again after she turns 3. It's a concrete number and maybe something she will better understand, rather than some abstract arbitrary day.
My daughter is a lot like yours and was really resistant to potty training until I finally just took the diapers off, stuck the underwear on, and let her have some accidents a few times. And we had tried every trick and every incentive in the world up until the point and everyone kept saying she'll train when she is ready, etc. but they didn't know her! I swear, she would still be in diapers today if I hadn't done what I did! But she was also a whole year older than your daughter is now, so I figured it was fine to say, enough was enough.
The thing is, she had quite a few accidents and wet panties on day 1. She didn't like it and wanted her diapers back, but I held firm and told her no. She still had a pull-up for sleeping but typically was dry when she woke up. On day 2 she had a couple of accidents, but also a couple of times got that "look" on her face that told me she knew the pee had to come out and she needed to do something about it, so I would escort her to the bathroom and make her sit on the potty, even as she was wailing and carrying on that she just wanted her diapers back. Once the pee ended up in the potty a few times, and she got praised and rewarded (stamp on a chart plus M&Ms) for it, she did great. By day 3, she didn't have any wet panties or accidents at all and was telling me she had to go sit on the potty to pee. And literally, that was it. Again, remember, she was also a whole year older than your daughter is now. But it's not like waiting that long made it harder - if anything, it was as easy as pie, once we got her to understand what she needed to do and she didn't have a choice any longer. She will be turning 5 in August and I can probably count on one hand the number of pee accidents she's had in the past year since getting trained.
So, like I said, you can see how it goes for a few more days, but if she senses that you are pressuring her too much, she is going to resist, and you will probably be better off taking a break, and trying again in a few more months.
