I think, 100% profit is not possible here! Since, it’s a decentralize market! So, maybe they are!

Forex market is a market that is managed by the participants. The largest participants have an impact on the market, and can have losses and income in the same way as small participants who enter into trade through intermediaries.
More experienced market participants have skills that, in their opinion, allow them to make profits more often than lose. But as we know, everything is unstable in the forex market.
