The words get used interchangeably, but they describe different time horizons, different skills, and very different odds.

Most people who think of themselves as investors are, in their actual behaviour, occasional traders wearing an investor's vocabulary - checking prices daily, reacting to news, and calling the decisions that worked out 'investing' and the ones that didn't 'a trade that didn't work out'.
An investor buys something expecting the underlying business or asset to create real value over years, and is paid for being patient enough to let that happen. A trader buys and sells based on expected near-term price movement, profiting from changes in price rather than from the asset itself becoming more valuable.
Neither is inherently better. They are different skills, with different tools, different time commitments and different odds of success for an ordinary person doing it part-time.
Because most of the damage done by first-time market participants comes from mixing the two: investing in something for the long term, then reacting to a bad week like a trader would, or trading actively while telling yourself a story about long-term conviction. Knowing which one you're actually doing changes what 'success' should even look like.

Two people buy the same stock. One reads the company's financials, decides the business is undervalued relative to its long-term prospects, and plans to hold for five years regardless of short-term price swings - that's investing. The other buys because the price has been rising all week and plans to sell within days if it keeps climbing - that's trading. If the price drops 8% the next day, the first person's plan is unaffected; the second person's entire thesis has just failed.
The costliest version of this mistake is calling a trade an investment after it goes wrong - 'I'm just going to hold it now and see' - when the original reasoning was about short-term price movement that has already been proven wrong. This turns a small, planned trading loss into an unplanned, unbounded one.
Write down whether your reasoning is about the business's long-term value or about near-term price movement. Do this before the trade, not after.
If you're trading, decide the price at which you're wrong and will sell, before you buy - not after the price has already moved against you.
If you're investing, judge the decision by whether the original reasoning about the business still holds, not by the current price.
If you do both, keep them in genuinely separate mental (or actual) accounts, so a trading loss can't quietly get relabelled as a long-term investment.
Whenever you're about to put money into something and haven't yet articulated why - use this to force the question.
Don't use this as a reason to avoid ever trading or ever investing - it's a classification tool, not a verdict on which approach you should take.
Academic research using large retail brokerage datasets - most notably studies by finance researchers Brad Barber and Terrance Odean - has repeatedly found that households trading most frequently earned meaningfully lower average returns than those trading least often, once costs and mistimed entries and exits were accounted for.
Activity itself is not a strategy, and more of it is not automatically better - the data points the other way.
