Staying low-key the best practice that you need to do after successfully win huge amount of money inside the gambling house. There's no need to broadcast any information about your lucky day as it can turned to not a good outcome we never know what inside those people who you talk about your money.
your opinioin is totally right, we must stay low-key after winning some , in gambling we must stay calm, dont put all in, dont use all money in 1 round, we must sparate to backup our lost too.
manage it like trading so we can gain our money not only gain our percent of profit.
