rpAmount = 100
ppCount = 10
rpResult=[]
rpRnds = []
rpRndSum = 0
for(let i=0;i<ppCount;i++){let rnd = Math.random();rpRndSum+=rnd;rpRnds.push(rnd);}
rpRnds.forEach((rnd)=>{rpResult.push(rpAmount*rnd/rpRndSum)})
console.log('rpResult',{rpResult,sum:rpResult.reduce((acc,val)=>{return acc+val})})

Core idea:
The weight is directly determined by the random number, not the amount.

Idea: Use the random function to randomly allocate each time. The red envelope value obtained each time is greater than 0.01 and less than the remaining amount - the remaining number of people * 0.01. The last person can get all the remaining money
