Raphael Lemkin's legal definition of genocide requires that it be intentional. Since he coined the word and drafted the UN Convention Against Genocide, I expect you won't contest it.
If Israel is intent on exterminating Gaza's Arabs, it's waging the least competent genocidal war in history:
Gaza city population figures:
1945: 34250
1982 100,272[108]
1997 306,113[109]
2007 449,221[3]
2012 590,481[3]
The entire Muslim world, on the other hand, has been quite proficient at decimating its minority populations:
Turkiye: 1.5m Armenians annihilated and millions of Greeks killed or displaced.
Syria, Iraq and Turkiye: wars of annihilation against their Kurdish minority.
ISIS' genocidal war against the Yazidis and Mosul's Christians.
And let's not forget the ethnic cleansing of the Jewish populations of Algeria, Tunisia, Libya, Egypt, Lebanon, Iraq, Yemen, Syria, Iraq from six figures to single digits or zero with expropriation of assets that dwarf what Arab refugees from Palestine lost in 1948-49 when their leaders told them to flee while their armies would be busy for a few weeks driving the Jews into the sea.

Genocide isn't a matter of numbers, but intentions. Hamas' orgy of livestreamed mass murder, rape, immolation and hostage taking on October 7 was genocidal because it put into practice the intentions proclaimed in Hamas' covenant. Israel has no such covenant and its targeting agents have spent countless hours on more than 30000 phone calls with Gazans to reduce civilian casualties. I know of no other army in human history that risks allowing its targets to escape together with those targets' human shields, surrendering the element of surprise in striking its enemy that started the war that broke a ceasefire that was in force on October 6.
