Any Successful, Day and Swing traders? How’d you do it?

I’ve been watching a lot of videos and taking notes and Ive made one successful swing trade(11%gain)and one successful day trade(2.5%). I just want to know if day and swing trading successfully is reliable long term if you are disciplined in sticking to a trade plan? Quick searches make it seem like most traders lose money. I guess I just want to know if it’s real and with good effort it can pay off versus just gambling. A goal would be to build enough to trade for a living but I’d be happy if I’d be making small positive gains in up to three trades per week.

Btw I’m trading with $1,530 since that’s 1% of my 401k investments. I plan to put gains from this in a separate index fund that I can use to pay off my mortgage early and maybe buy a boat ;).

Also if it did work out for you, what learning resource would you recommend? I’ve learned a lot from youtubers the boiler room and raynar.
