When Hamas were formed in 1987, they had minimal support from Palestinians. But in 2021, support for Hamas dramatically increased as AP News reported:

In 2022, respected Palestinian pollster Khalil Shikaki and his Palestinian Center for Policy and Survey Research (PCPSR) carried out a survey looking at Palestinian support for armed groups. Main takeaways below:
• 72% of Palestinians support forming more armed groups in West Bank
• in Gaza, 84% of respondents supported concept of armed groups taking NO orders from the Palestinian Authority. This is HIGHER than in the West Bank where 65% supported the idea.

So, the support for Hamas, Lion's Den and other Palestinian armed groups is there from the Palestinian population. A minority do not support them.
At the same time, Palestinian support for the Fatah party led by President Abbas in the West Bank has collapsed to as low as 14%. Abbas is struggling to keep control of the Palestinian Authority territory in the face of support for armed groups such as Hamas.
Important to note that Abbas' Fatah party also has an armed wing - Al-Aqsa Martyrs Brigade. So, there is a LOT of Palestinian support for terrorist groups overall.
So, not all Palestinians support Hamas. But it is NOT wrong to say that Hamas have the majority Palestinian support. That may or may not change in future.
