Is selling on Amazon worth it?

I keep seeing lots of videos about selling on Amazon through retail arbitrage and my interest is piqued. Is it worth it? I’d love to hear about other people’s experiences, especially if they did it using retail arbitrage.

A little info… I have some money for investment, but I’m not willing to spend thousands. Also, I’m a stay at home parent just looking to make a little money, not make 6 figures. Currently I make $0/hour being at home, so even cleaning $250-$500 would be a huge win for me.
