There is no ambiguity in Torah about the requirement of a miraculous redemption, as this is explicit psikim that chazal maintain their literal reading.
This is such a clear point in Torah that the Rambam includes it in the 13 ikarim and claims anyone who doesn’t believe in the miraculous redemption is no longer part of the am yisroel.
Beyond that, if there is any confusion in identifying if any redemption-like events qualify as “miraculous enough”, we are repeatedly taught by chazal through to poskim rishonim and achronim that we must presume that the claim is fraudulent and we must reject such claims specifically because there will in reality be no doubt when the real redemption happens and there will be no necessity for us Jews to figure it out as the redemption will happen regardless of us realizing it. This is so clear that the Rambam emphasizes in Yad Chazukeh that no signs or miracles should fool us into believing a moshiach sheker, rather the only “sign” we should follow is doing tshiva, a firm perquisite to the real geila (because we are always allowed/required to do tshiva, so no risk of following a moshaich sheker).
The saddest part of this whole conversation is that everything I wrote is both clear and emphatically expressed throughout our Torah, yet so many fools don’t even bother to read them nor do they listen to the actual published teaching of our Gedolim regarding the subject and how critical these point are to even starting life as a Jew.
