UGH you’re just like my sister then! See I played runescape after taking a typing class in elementary school, so in class I got like 5 wpm, then over a summer of doing nothing but playing rune scape whenever I was able (usually by staying up late after everyone went to sleep) I got up to 25, and it just kept getting faster over the years as I kept playing other online game.
My older sisters didn’t have typing classes before they started doing IM chat rooms and stuff though. So my sister somehow types at 90 WPM by doing this cursed 2 finger chicken peck thing. She types way faster than me by just using 2 fingers on each hand and it always confuses the heck outta me.
