Unless you are a multimillionaire, no it will not be your wealth being redistributed. The problem is not well-off people driving their Teslas around and taking two vacations a year, it is the relatively few people hoarding such obscene levels of wealth that their personal holdings dwarf those of entire lower economic classes of people. More than they could possibly need for 1000 lifetimes.
If you expropriate the entire wealth of the top 0.1% (6 trillion dollars), it will last around 2-3 years (social security/medicare/medicaid expenditure of the US is more than 2 trillion dollars per year). The "relatively few people" are of course rich, but they are, as you have said, relatively few. Most of the taxable money are made by the middle class.
