Anything is possible with enough investment. More difficult today though, with the massive shortages and order limits when buying card to mine with now.
Yes. So, It's not too late to start. Store your capital, there still have lots of time ahead. Mining will be the best business investment for a while. I don't get why anyone would say it isn't profitable. As more anyone invest, as they get more profits.
The ROI is incredible. ASICs are still a sound investment. I have more invested in ASICS though, but I am mining with a few gpu's.
I can see where folks would like to spread fud though. You can't find gpus anywhere now.
