Do you have a source for amp standards? My limited search suggests much of EU have 10A plugs. Also here in AU our standard is also 10A along with our NZ family.
A low end range has 16K BTU for the oven, plus 4 10K burners = 56,000 BTU = 16.5kWatt.
But the 50A outlet can only deliver 50 * 240 * 80% = 9,600 watt.
