Converting JS/Ruby regular expression into Python regex

I wanted to extract numbers from text and I stumbled upon this answer.

However, the regular expression provided

(?:^|\s)(?=.)((?:0|(?:[1-9](?:\d*|\d{0,2}(?:,\d{3})*)))?(?:\.\d*[1-9])?)(?!\S)

doesn't work properly in Python.

For example:

import re
text = "Compared to 2019, the revenue increased from 934,000$ to 1.5 million$ in 2020."
rx =  r'(?:^|\s)(?=.)((?:0|(?:[1-9](?:\d*|\d{0,2}(?:,\d{3})*)))?(?:\.\d*[1-9])?)(?!\S)'
print(re.findall(rx, text))

returns ['1.5'] while I expect it to return ['2019', '934,000', '1.5', '2020'].

I would appreciate any help with this issue.
