A few fundamentals that matter far more than expensive gear when you're just starting to take photography seriously.

The single biggest factor in a good photo is light, not equipment. Soft, indirect light (early morning, late afternoon, or open shade) is far more forgiving than harsh midday sun or mixed indoor lighting. Before worrying about camera settings, start by paying attention to where the light is coming from and how soft or harsh it is.
Simple composition habits make an outsized difference: the rule of thirds (placing your subject off-center rather than dead-center), leaving room in the frame for your subject to "look into," and paying attention to what's in the background so it doesn't distract from the subject.
Aperture, shutter speed, and ISO (the "exposure triangle") are worth learning, but they matter less than light and composition when you're starting out. Shooting in a semi-automatic mode while you build an eye for light and framing is a reasonable place to begin.
Consistent practice, followed by honestly reviewing what worked and what didn't, improves your eye faster than reading about technique. Try to identify specifically why a photo you like works — the light, the angle, the moment — rather than just noting that you like it.
