Credit card question. (First credit card)

I got my first ever credit card to establish credit. So I got approved for 3,000 but will only spend like 500 or 600 and never go above that. So the due date every month is on the 2nd. So every month on the 1st I will pay it in full and have a 0 balance on the 2nd. And that’s how I get better credit right? So make some small payments during the month, pay in full on the 1st, so the next day 0 balance, then repeat. This way I will get better credit?

Also, my credit card is like 27% something interest so I will literally never let my balance go from month to month 😬

Any advice greatly appreciated!
