With the first reason I partially disagree. You don’t have to put 6-figure amount in order to become a millionaire. If we assume that a person becomes a millionaire when they reach $1,000,000 then even with 4 or 5-figure amount would get you good start and IF you invest them properly early. For example if you invested $20 000 on Tesla in 2019 August that would be around 434 stocks after the split or about 88 stocks same worth. Since Tesla is growing rapidly I would predict that it will reach 2400$ price by the end of 2025. Thus you would make around $1,085,000. Of course anything can happen and nothing is guaranteed but that’s theoretically possible and probably probable.
