Please keep up the hope! While it is more difficult for Viets to get PR in Singapore, it is certainly not impossible - I knew at least 5+ who managed to get it before 30 years old albeit they are very high-flying people.
My own observations + conclusion is that if the quota is aimed at maintaining racial ratio (which is 75% Chinese, 15% Malays, 8% Indians, 2% Others), then the actual approved PRs ratio would be very different. It's much more likely that the Others category is around 5-10%, Indian 10%, and Chinese 80%+, which explains my own anecdotal observation as well.
This is because you also need to take into account the existing foreigner nationality/ethnic composition, and the existing total fertility rate of the 4 race categories of Singapore.
Let's look at the argument from a macro-level perspective:
1. As of 2020-2021, there are more than 2 millions foreign nationals in Singapore, of which more than 1 millions are Malaysians. Around 500k are from China, 300k are from South Asia, the rest are from various different ASEAN countries and a minority (I would guess 50k?) are non-Asian.

Of course, we should also think of the distribution by valid working passes for PR (EP, SPass...) - which still shows that at least 65% of these pass holders are Chinese (mostly Malaysians/PRC), and 25% are South Asians. An approximately 15% are Others, which I think can be subdivided by ASEAN, non-ASEAN Asians, and non-Asians.
This figure is approximated and supported by the following article, so take it with a grain of salt:

Note that based on observations, the population of foreign Malays from Malaysia/Indonesia is not substantial (a large majority are not either not holding strong enough working pass, or will not prefer Singapore at all due to their native countries' preferential treatments). I would take at most 1-2% of valid working passes statistics as Malay, and I believe almost all of them would get PRs/citizenships if they wish due to the quota.
2. The TFR of Chinese as of now is below 1, TFR of Indians is around 1-1.1 approximately, while the TFR for Malays is 1.8-1.9 approximately. All of these figures are below replacement rates of 2.1, and meaning that the SG government would prefer Chinese, then Indian, then Others, for PR applications.
Now, with these hypotheses in mind, let's revisit the existing quota for PRs + Citizenships which amount to 35000 and 20000 respectively every year.
This means that at least 28000-29000 PRs are granted each years to ethnic Chinese, 3000-4000 to Indians, and approximately 3000+ to non-Chinese and non-Indians. I have plotted graphs and visualize that by using this approximate figure, the CMIO quota would remain largely the same over the next 20-30 years.
There are 200k EPs in Singapore, 180k SPass in Singapore. The approximate annual PR applications is around 100k. If you take into account my figures, and assume normal distributions for PR applications, around 70k applications are Chinese, 20k are Indian, and 10k are Others.

So the competition for Chinese ethnic is 1 against 2, for Others is 1 against 3.5, for Indian is 1 against 5. I rounded up the number as a way to visualize the statistics.
It's also very likely that the competition ratio is 1:3 for non-Chinese Asians, and 1:4 for non-Asians. Within the figures for Chinese ethnics, there will be a slight preference for Malaysian/Indo Chinese as well.
Taking into account the ratio, this means that I don't think it is significantly easier for Malaysian Chinese to get PRs (although they are definitely preferred). With the current policies, non-Chinese Asians are still somewhat preferred over non-Asians.
And there are always options to marry a local Singaporean or invest 3 million dollars in a Singapore entity if you want quicker way to get PR.
