Why does my male coworker tell me of my mistakes in work?

The work that we do in my workplace is pretty manual with data inputting and I recently have been making some mistakes in my workplace that my male colleague in my team has pointed out and told me about just (he doesn’t tell anyone else each time just me)

Though each time it seems like he isn’t is more annoyed with me even though I haven't been in the business for long (between 6 months but less than a year) Does he hate me or does it seem like he is deliberately looking for mistakes that I make? Or am I reading too much into it?
